[On Figure arrow D is pointing to the:] Supraspinatus tendon Infraspinatus tendon Teres minor tendon Subscapularis tendon Biceps muscle None Comment . [On Figure the following images were acquired WITH fat suppression:] 1, 2, and 3 4, 5, and 6 1 and 2 3, 4, 5, and 6 None Comment . [On Figure arrow D is pointing to the:] Portal vein Splenic vein Renal vein Superior mesenteric vein None Comment . [Decreasing the receiver bandwidth (narrow BW):] Decreases the SNR Inverts the SNR Increases the SNR Has no effect on the SNR None . [In imagers that are magnetic field shielded:] Any metallic objects can enter the scan room There is no fringe field and the magnetic field is contained within the bore The fringe field is confined but still exists Care should be taken to prevent ferromagnetic materials from entering the field a and b c and d None . [Complete saturation is a condition where:] Not enough time is given to allow the T2 decay to complete The image becomes brighter Longitudinal magnetization is not allowed to recover between excitations Proton density effects predominate None . [On Figure arrow G is pointing to the:] Anterior cruciate ligament (ACL) Posterior cruciate ligament (PCL) Lateral meniscus Medial meniscus None Comment . [On Figure arrow L is pointing to the:] Superior vena cava Inferior vena cava Pulmonary artery Aortic arch None Comment . [Gradient speed (rise time) and strength (amplitude) is measured in units of: 1. mT/M 2. G/cm 3. T/m/s 4. μs 5. %] 1 only 1 and 2 only 3 only 4 only 5 only None . [Tissues with short T1 relaxation times (like fat and gadolinium = enhancing structures) appear ______ as compared to normal structures on T1-weighted images.] Hyperintense/brighter than Hypointense/darker than Isointense/the same signal intensity as Dark None . [BEFORE the publication of the “Contrast Media Update” by the ACR in 2010, contraindications for using gadolinium included: 1. Sickle cell crisis and hypertension 2. Pregnancy and breast-feeding mothers 3. High BUN and creatinine 4. Low GFR 5. Renal insufficiency and/or acute renal injury 6. None known] 6 only 1, 2, and 3 only 4 and 5 only 1, 2, 3, 4, and 5 only None . [In a superconducting magnet, the magnetic field strength is increased by increasing the:] Amount of cryogens Temperature Internal pressure Turns of wire None . [Blood flow at the area of a stenosis (vascular narrowing) is known as:] Laminar flow Accelerated flow Vortex flow Turbulent flow None . [The accepted standard of care for the detection of intraocular ferrous foreign bodies is:] Computed tomography MRI Plain film Visual examination None . [If you determine that an ADULT patient requires CPR, your first action should be to:] Wash your hands Call for help Administer two rescue breaths Begin cardiac compressions None . [When venipuncture is performed:] The technologist is not responsible for obtaining patient history because the exam was ordered by a physician. The contrast agent should NEVER be flushed through the syringe, any tubing used, and the needle before injection The contrast agent must be cooled to make it easier to inject The contrast agent must ALWAYS be flushed through the syringe, any tubing used, and needle before injection to avoid the administration of air into the vein None . [On a typical diffusion image (Figure, left), the high signal indicated by arrowE represents:] Chronic infarct Old stroke Transient ischemic attack (TIA) Early (hyperacute) infarct None Comment . [Doubling the number of signals averaged (NSA) will:] Decrease the SNR Increase the SNR by the square root of 2 Double the SNR Not affect the SNR None . [On Figure arrow F is pointing to the:] Caudate nucleus Lentiform nucleus Internal capsule Thalamus None Comment . Time's up
