| Question 1: What parameters are most likely to generate T2-weighted FLAIR image? |
| Reference: | Rydberg JN, Hammond CA, Grimm RC, et al. Initial Clinical Experience in MR Imaging of the Brain with a Fast Fluid-attenuated Inversion-Recovery Pulse Sequence. Radiology 1994: 193:173-180. |
| Choice A: | Long TR, long TE, and long TI. |
| Choice B: | Long TR, long TE, and short TI. |
| Choice C: | Long TR, short TE, and long TI. |
| Choice D: | Long TR, short TR and short TI. |
| Question 2: What kind of MR image is most commonly acquired after administration of the Gd-based contrast agent? |
| Reference: | Kirsch JE, Basic Principles of magnetic resonance contrast agent. Top Magn Reson Imaging. 1991 Mar; 3(2): 1-18. PMID: 2025431. |
| Choice A: | T2W image because T2 is shortened by the contrast agent. |
| Choice B: | T1W image because T1 is increased by the contrast agent. |
| Choice C: | T1W image because T1 is shortened by the contrast agent. |
| Choice D: | Proton density-weighted image because contrast agent does not have any effect to brain tissues. |
| Question 3: Which modalities can be used for evaluating the internal structure of the spinal cord? |
| Reference: | ACR-ASNR-SCBT-MR-SSR Practice Parameter for the Performance of Magnetic Resonance Imaging (MRI) of the Adult Spine (https://www.acr.org/-/media/ACR/Files/Practice-Parameters/MR-Adult-Spine.pdf) |
| Choice A: | Plain film radiography |
| Choice B: | CT |
| Choice C: | MRI |
| Choice D: | Both CT and MRI |
| Question 4: Which method is specifically useful for improving image quality near spinal fixation? |
| Reference: | ACR-ASNR-SCBT-MR-SSR Practice Parameter for the Performance of Magnetic Resonance Imaging (MRI) of the Adult Spine (https://www.acr.org/-/media/ACR/Files/Practice-Parameters/MR-Adult-Spine.pdf) |
| Choice A: | Traditional fat suppression |
| Choice B: | T2*-weighted imaging |
| Choice C: | High bandwidth scanning |
| Choice D: | Echo Planar Imaging (EPI) |
| Question 5: The Prostate Imaging – Reporting and Data System (PI-RADS) v2.1 (2019) provides minimum acceptable technical parameters for prostate multiparametric magnetic resonance imaging (mpMRI). Which imaging technique is optional for a clinical prostate mpMRI examination? |
| Reference: | PI-RADS® Prostate Imaging – Reporting and Data System, 2019, Version 2.1. https://www.acr.org/Clinical-Resources/Reporting-and-Data-Systems/PI-RADS |
| Choice A: | T1-weighted imaging |
| Choice B: | T2-weighted imaging |
| Choice C: | Diffusion-weighted imaging |
| Choice D: | Proton magnetic resonance spectroscopic imaging |
| Question 6: Diffusion-weighted imaging (DWI) is the primary determining sequence for suspicious prostate lesions in the peripheral zone. Which of the following statements is not in the technical specifications for DWI in the PI-RADS? |
| Reference: | PI-RADS® Prostate Imaging – Reporting and Data System, 2019, Version 2.1. https://www.acr.org/Clinical-Resources/Reporting-and-Data-Systems/PI-RADS |
| Choice A: | DWI is acquired using one low b-value set at 0100 sec/mm2 and one intermediate b-value set at 8001000 sec/mm2. |
| Choice B: | A high b-value ( 1400 sec/mm2) is not mandatory. |
| Choice C: | A high b-value can be calculated from the low and intermediate b-value images. |
| Choice D: | The ADC map is calculated using the low and intermediate b-values. |
