  2. MRI contrast agent - Wikipedia

    en.wikipedia.org/wiki/MRI_contrast_agent

    A contrast agent usually shortens, but in some instances increases, the value of T1 of nearby water protons thereby altering the contrast in the image. Most clinically used MRI contrast agents work by shortening the T1 relaxation time of protons inside tissues via interactions with the nearby contrast agent.

  3. Endorectal coil magnetic resonance imaging - Wikipedia

    The technique has demonstrated higher accuracy than other modalities in assessing seminal vesicle invasion and extra-capsular extension (ECE) of prostate cancer (96% and 81% respectively). Endorectal coil MRI is useful for determining the extent of spread and local invasion of cancers of the prostate, rectum, and anus. [2]

  4. Radiocontrast agent - Wikipedia

    en.wikipedia.org/wiki/Radiocontrast_agent

    Iodinated contrast contains iodine.It is the main type of radiocontrast used for intravenous administration.Iodine has a particular advantage as a contrast agent for radiography because its innermost electron ("k-shell") binding energy is 33.2 keV, similar to the average energy of x-rays used in diagnostic radiography.

  5. Pyelogram - Wikipedia

    en.wikipedia.org/wiki/Pyelogram

    Pyelogram (or pyelography or urography) is a form of imaging of the renal pelvis and ureter. [1]Types include: Intravenous pyelogram – In which a contrast solution is introduced through a vein into the circulatory system.

  6. Magnetic resonance neurography - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance_neurography

    The most significant impact of magnetic resonance neurography is on the evaluation of the large proximal nerve elements such as the brachial plexus (the nerves between the cervical spine and the underarm that innervate shoulder, arm and hand), [9] the lumbosacral plexus (nerves between the lumbosacral spine and legs), the sciatic nerve in the pelvis, [10] as well as other nerves such as the ...

    en.wikipedia.org/wiki/Interventional_radiology

    A number of diagnostic tests can be performed through minimally invasive methods, to determine whether a patient's chronic pelvic pain is a result of pelvic varicose veins. These tests include: Pelvic and transvaginal ultrasound; Pelvic venogram; Computed tomography (CT) Magnetic resonance imaging (MRI)

  8. Computed tomography of the abdomen and pelvis - Wikipedia

    en.wikipedia.org/wiki/Computed_tomography_of_the...

    Abdominal imaging is associated with many potential uses for the different phases of contrast CT.The majority of abdominal and pelvic CT's can be performed using a single-phase, but the evaluation of some tumor types (hepatic/pancreatic/renal), the urinary collecting system, and trauma patients among others, may be best performed with multiple phases.

  9. Magnetic resonance cholangiopancreatography - Wikipedia

    Negative oral contrast such as pineapple juice, [1] date syrup, ferumoxsil, Açaí juice and water are useful in decreasing T2 signal intensity, thus minimising signals from stomach and duodenum from interfering with signals from the biliary system. [6] MRCP makes use of heavily T2-weighted MRI pulse sequences.
