Magnetic Resonance Imaging (MRI)
Goal Highly detailed anatomical images
  • What Does It Do?
  • Strong magnetic field is applied, causing the
    nuclei within the patients body to rotate and
    align
  • Scanner detects, records, and combines the
    different rotating fields into a single image
  • Gradients in all directions are combined to
    create a 3D image
  • Strong contrast between different soft tissues
    within body
  • Better at producing images of brain, muscles,
    heart, cancers than CT or x-rays
  • Applications
  • Used to distinguish pathological tissue from
    normal tissue
  • Comparable resolution, much better contrast
    resolution (between arbitrarily different but not
    identical tissues) than CT
  • Advantages
  • Harmless to patient
  • What it uses
  • Strong magnetic fields
  • Non-ionizing radiation

9
Magnetic Resonance Imaging (MRI)Terminology
  • Parameters of Image Acquisition
  • Edema
  • TE echo time
  • TR repetition time
  • TI inversion time
  • Time between inversion and excitation pulses
  • Abnormal accumulation of fluid beneath the skin
    or in cavities of the body
  • Caused by increased secretion of fluid into the
    interstitium or impaired removal of fluid

10
Magnetic Resonance Imaging (MRI)Basic Scans
  • T1-weighted MRI scan
  • T2-weighted MRI scan
  • Highlights fat deposits
  • Water dark fat bright
  • Good grey v. white matter contrast
  • Commonly run clinical scan
  • Short TE short TR
  • Highlights fluids
  • Fat dark water light
  • Good for imaging edema
  • Heavily used for clinical scans of cerebral
    spinal fluid
  • Long TE long TR

T2-weighted MRI scan
Spin density weighted MRI scan
  • Gradient Echo (GRE) sequence
  • Additional loss over T2 decay
  • Air/tissue boundaries susceptible
  • Increases contrast of specific tissues
  • Long TE long TR
  • No contrast from either T1 or T2 decay
  • Uses spin echo (sometimes gradient echo)
    sequences
  • Short TE long TR

11
Magnetic Resonance Imaging (MRI)Specialized Scans
  • Diffusion MRI scan
  • Fluid Attenuated Inversion Recovery (FLAIR)
  • Diffusion tensor imaging (DTI) enables diffusion
    to be measured in multiple directions
  • Make brain maps of fiber directions
  • Examine connectivity of different regions of
    brain
  • Examine areas of neural degeneration and
    demyelination
  • Inversion-recovery pulse sequence that nulls
    fluid signals
  • Free water dark edematous tissue bright
  • Most sensitive way to evaluate brain for
    demyelinating diseases
  • Carefully-selected TI allows signal from any
    particular tissue to be suppressed
  • Conversion of T2-weighted sequence via additional
    radio frequency pulse and manipulation of
    magnetic gradients

Functional MRI (fMRI)
  • Measures signal changes in the brain due to
    changing neural activity
  • Low resolution, rapid rate scans
  • BOLD (Blood-Oxygen-Level Dependent) effect
  • Increases in neural activity cause changes in MR
    signals via T2 changes
  • Increased neural activity increases demand for
    oxygen
  • Vascular system overcompensated, increasing
    oxygenated hemoglobin
  • High resolution 3D maps of venous vasculature
    within neural tissue

Real-Time MRI
  • Continuous monitoring ("filming") of moving
    objects in real time
  • Should help provide information about diseases of
    the joints and heart
  • May make MRI examinations easier and more
    comfortable for patients

12
Magnetic Resonance Imaging (MRI)Medical
Applications
  • Interventional Therapy
  • Radiation Therapy Simulation
  • MRI images used to guide minimally invasive
    procedures both intraoperatively and
    interactively
  • No ferromagnetic instruments used
  • Some specialized systems allow imaging concurrent
    with surgery
  • Usually, surgical procedure is temporarily
    interrupted so MR images can be acquired to
    verify success/guide subsequent surgical work
  • MRIs used to specifically locate tumors within
    body in preparation for radiation therapy
    treatments
  • Patient placed in specific, reproducible, body
    position and scanned
  • MRI system computes precise location, shape and
    orientation of the tumor mass, correcting for
    spatial distortion inherent in the system
  • Patient is marked/tattooed with points that, when
    viewed in specified, reproducible body position,
    permit precise triangulation for radiation therapy

13
Magnetic Resonance Imaging (MRI)
  • What is MRI Compatibility?
  • Safety Concerns
  • MR-Safe device or implant that is completely
    non-magnetic, non-electrically conductive, and
    non-RF reactive
  • Titanium and its alloys
  • MR-Conditional device that is safe, provided
    the safety conditions are defined and observed
  • MR-Unsafe objects that are significantly
    ferromagnetic and pose a clear and direct threat
    to persons and equipment within the magnet room
  • Patients always asked for complete information
    about all implants prior to entering the MRI suite
  • Radio frequency energy
  • Powerful radio transmitter can heat the body to
    the point of risk of hyperthermia in patients
  • Peripheral Nerve Stimulation
  • Rapid switching on and off of the magnetic field
    gradients may cause nerve stimulation
  • Acoustic noise
  • Appropriate ear protection is necessary for
    anyone inside MRI scanner room during examination
  • Cryogens
  • Cryogenic (extremely cold) liquids enable
    superconducting capabilities of the
    electromagnetic coils
  • MRI support rooms should be equipped with
    pressure relief mechanisms and an exhaust fan in
    case of a quench (shut-down of superconduction
    electromagnet)
  • Pregnancy
  • Increasingly important for diagnosing and
    monitoring congenital defects of the fetus (no
    contrast agents used)
  • Fetal tumors (primarily teratomas)
  • Facilitating open fetal surgery
  • Other fetal interventions
  • Planning to safely deliver and treat babies whose
    defects would otherwise be fatal

Positron Emission Tomography-Computed Tomography
(PET-CT)
Goal Precise localization of metabolic functions
  • What Does It Do?
  • How Does It Work?
  • Hybrid modality of PET and x-ray CT
  • Takes both types of images sequentially, in the
    same session
  • Images can be combined into a single 2D or 3D
    superposed image
  • Detecting changes in molecular activity
  • Reveal primary tumors
  • Detect metastases
  • Quantify uptake
  • Improves accuracy in oncology, surgical planning,
    radiation therapy, cancer staging
  • Increased image quality, speed, and accuracy of
    diagnosis
  • Patient fasts for 4 hours or more
  • Intravenous bolus (tracer) injected patient's arm
  • 1-2 hours later, patient placed into PET-CT,
    usually with arms at the sides or above the head
  • Automatic bed moves head first into the gantry,
    first obtaining a topogram (whole body flat
    sagittal section)
  • Operator uses PET-CT console to identify patient
    and examination, selects the scanning parameters
    and starts image acquisition period
  • Patient automatically moved head-first into CT
    gantry, where x-ray tomogram is acquired
  • Patient automatically moved through PET gantry,
    parallel to CT gantry PET slices acquired
  • Software reconstructs/aligs PET and CT images
  • Whole body scan (mid-thigh to top of head) takes
    5-40 min

19
Positron Emission Tomography-Computed Tomography
(PET-CT)
  • Positron Emission Tomography
  • X-ray Computed Tomography
  • Uses radionucleotide decay to generate 3D image
    of functional processes in the body
  • Detects gamma rays emitted by a positron-emitting
    radionucleotide ("tracer")
  • Tracer enters patient's body via a biologically
    active molecule
  • FDG is a tracer used to display metabolic
    activity of tissue in terms of regional glucose
    uptake
  • Computer analyzes location/concentration of
    tracer within patient to construct 3D images
  • Uses computer processed tomography to generate 3D
    images from a collection of 2D x-ray images taken
    around a single axis of rotation
  • Tomography imaging by sections
  • Supplements x-rays and medical ultrasonaography
  • Used in preventative/screening medicine

Ultrasound
  • What is Ultrasound?
  • Applications
  • Cyclic sound pressure with a frequency (20 kHz -
    200 MHz) greater than the upper limit of human
    hearing (typically 20,000 hertz in healthy young
    adults)
  • Uses many different fields to penetrate a medium
    and measure the reflection signature or supply
    focused energy
  • Reflection signature can reveal details about the
    inner structure of the medium
  • This property is used by bats to locate prey
    while hunting
  • Most well-known application is use in sonography
    to image a fetus in a human womb
  • Diagnostic sonography (AKA ultrasonography)
    ultrasound-based diagnostic imaging technique
    used to visualize subcutaneous body structures
    such as tendons, muscles, joints, vessels and
    internal organs for possible pathology or
    lesions)
  • Able to determine size, structure, and any
    pathological lesions using real-time tomographic
    images
  • Soft tissue imaging
  • Cardiac (heart)
  • Renal (kidney)
  • Hepatic (liver and gallblader)
  • Muscuko-skeletal (muscles, ligaments, tendons)
  • Ophthalmic (eyes)
  • Superficial (just under the skin) structures
  • Ex testicles, thyroid, salivary glands, lymph
    nodes
  • Guiding interventional procedures in real time
  • Fine needle aspiration/biopsy (FNA/NAB)
    diagnostic procedure
  • Biopsy of masses for cytology or histology
    testing in breast, thyroid, liver, kidney, lymph
    nodes, muscles, joints

27
Ultrasound
  • Obstetric Imaging
  • Emergency Ultrasound
  • Used to identify many conditions harmful to both
    mother and fetus
  • Risk of leaving such conditions undiagnosed is
    far greater than the small risk associated with
    undergoing the actual US scan
  • Primary uses
  • Assess gestational age
  • Confirm fetal viability
  • Determine location of fetus, intrauterine v.
    ectopic (displaced anywhere besides uterine wall)
  • Check the location of the placenta in relation to
    the cervix
  • Detect multiple pregnancies
  • Detect major physical abnormalities
  • Assess fetal growth for evidence of intrauterine
    growth restriction (IUGR)
  • Check for fetal movement and heartbeat
  • Determine the sex of the baby
  • Specialized application by emergency responders
    to guide immediate first aid care
  • Pros
  • Images muscle, soft tissue, and bone surfaces
    well particularly good at delineating interfaces
    between solid and fluid-filled spaces
  • Renders "live" images, helps narrow down problem
    area
  • Determines severity and sources of trauma within
    region
  • Portable, narrowly-focused, easy to use
  • Cons
  • Cannot penetrate bone
  • Depth of penetration limited, especially in obese
    patients
  • Operator-dependent (high skill needed for good
    quality images and accurate diagnoses)
  • Scanning methodologies
  • Focused Assessment with Sonography for Trauma
    (FAST)
  • Detects internal bodily fluid in between organs
    in cases of blunt abdominal trauma
  • Screening test for blood around the heart or
    abdominal organs after trauma

28
Ultrasound
  • Biomedical Applications
  • Detection of pelvic abnormalities, involving
    abdominal/vaginal/rectal US
  • Break calculi (stones formed in the body) into
    fragments small enough to be passed without
    excessive difficulty via lithotripsy
  • Ablate tumors non-invasively via High Intensity
    Focused Ultrasound (HIFU)
  • Magnetic Resonance-Guided Focused Ultrasound
    (MRgFUS) guided by MRI, a lower frequency
    (250-2000 kHz) than medical diagnostic ultrasound
    is applied in significantly higher time-averaged
    intensities
  • Acoustic Targeted Drug Delivery (ATDD) enhanced
    transportation of molecules across specified
    tissues via high frequency ultrasound (frequency
    1-10 MHz sound intensity 0-30 watts/cm2)
  • Cataract treatment via phacoemulsification
    (surgery in which the eye's internal lens is
    emulsified with an ultrasonic handpiece and
    aspirated from the eye aspirated fluids replaced
    with balanced salt solution)
  • Low-intensity pulsed ultrasound used to stimulate
    bone and tooth regeneration, disrupt blood-brain
    barrier for drug delivery
  • Ultrasound-guided sclerotherapy and endovenous
    laser treatment
  • Ultrasound-guided sclerotherapy ultrasound is
    used to visualize the underlying vein, allowing
    the physician to deliver and monitor the
    injection of the vein-shrinking drug
  • Endovenous Laser Treatment (ELT)
    minimally-invasive ultrasound-guided technique
    used to treat varicose veins with laser energy
  • An optical fiber is inserted into the vein to be
    treated, a laser light is shone into the interior
    of that vein, causing the vein to contract
    optical fiber is slowly withdrawn
  • Elastography non-invasive method in which
    stiffness or strain images of soft tissue are
    used to detect and classify tumors
  • When a mechanical compression or vibration is
    applied, the tumor deforms less than the
    surrounding tissue (strain in the tumor is less
    than that in the surrounding tissue)
  • Elasticity can discern health from unhealthy
    tissue in specific organs/growths
  • Ultrasound Identification (USID)
  • Real Time Locating System (RTLS) or Indoor
    Positioning System (IPS)
  • RTLS used to wirelessly track and identify the
    location of objects in real time
  • Does not include speed, direction, or spatial
    orientation
  • IPS network of devices used to wirelessly
    locate objects or people inside a building
  • Nonlinear propagation effects
  • US waves usually display nonlinear propagation
    (distortion) due to their high amplitude to
    wavelength ratio
  • Safety Concerns
  • Occupational exposure to ultrasound in excess of
    120 dB may lead to hearing loss
  • Exposure in excess of 155 dB may produce heating
    effects harmful to the human body
  • Exposures above 180 dB may lead to death
  • Recommended to avoid routine use of ultrasound
    scans in low risk pregnancies
