Welcome to your CT Scan NAME: EMAIL: [A patient in shock may exhibit which of the following symptoms? 1. tachycardia 2. rapid, shallow breathing 3. cyanosis] 1 only 1 and 2 only 1 and 3 only 1, 2, and 3 None . [The Stanford type A dissecting aneurysm affects which portion of the aorta?] ascending thoracic descending thoracic abdominal bifurcation None . [Which of the following is used as the IV-administered radiopharmaceutical during a PET-CT fusion examination?] technetium T c 99m iodine I 131 fludeoxyglucose F 18 (FDG) strontium chloride Sr 89 None . [The range of serum iodine concentration for ade- quate tissue opacification during contrast-enhanced CT examinations is:] 2-8 mg/mL 12-20 mg/mL 30-42 mg/mL 75-105 mg/mL None . [The ability of an MSCT system to freeze motion and provide an image free of blurring is called:] in-plane spatial resolution longitudinal spatial resolution temporal resolution contrast resolution None . [Which of the following statements regarding pre- detector collimation of the CT x-ray beam is true?] Pre-detector collimation reduces patient radiation dose. Pre-detector collimation reduces the production of scatter radiation. Pre-detector collimation determines the scan field of view (SFOV). Pre-detector collimation removes scatter radiation before it reaches the detectors. None . [Number 2 on the figure corresponds to which of the following?

[On the basis of the information provided on the graph in the figure, which of the following statements is true? Fig.] The limiting resolution in section A is less than that in section B. The signal-to-noise ratio (SNR) of section A is greater than that of section B. The effective width of section B is greater than that of section A. Section B is isotropic in dimension. None Comment . [The section thickness that would demonstrate the greatest detail of the paranasal sinuses is:] 3 mm 5 mm 7 mm 10 mm None Comment .

[Which of the following phases of renal contrast enhancement best demonstrates transitional cell carcinoma (TCC) of the bladder?] early arterial corticomedullary nephrographic early arterial None . [Which of the following types of isolation techniques protects against infection transmitted through fecal material?] acid-fast bacillus isolation contact isolation enteric precautions drainage-secretion precautions None .
