Question 6# Print Question

Which of the following statements about multi-parametric prostate MRI is TRUE?

A. Malignant areas within the prostate have a high signal intensity on T2-weighted MRI
B. There are increased levels of citrate in cancerous prostatic tissue on MR spectroscopy
C. There are increased levels of choline in cancerous prostatic tissue on MR spectroscopy
D. Multiparametric MRI does not employ gadolinium-based contrast therefore it is a safe test in patients with renal failure
E. The T2-weighted sequence can be regarded as a functional form of imaging


Question 7# Print Question

Which of the following statements is INCORRECT?

A. Clear cell renal cell carcinoma generally appears hyperintense on T2-weighted MRI
B. Simple renal cysts appear hyperintense on T1-weighted MRI
C. MRI is better than CT when assessing for the extent of a venous tumour thrombus
D. The main MRI feature indicating potential malignancy in a renal mass is contrast enhancement
E. Oncocytomas show a variable low to moderate signal intensity on T1-weighted MR images


Question 8# Print Question

All of the following agents can be used for a dynamic renography study, except:

A. 123Iodine-labelled ortho-iodohippurate
B. 99mTechnetium-labelled dimercaptosuccinic acid
C. 99mTechnetium-labelled diethylene triamine pentaacetic acid
D. 99mTechnetium-labelled mercaptoacetyltriglycine
E. 99mTechnetium-labelled ethylene dicysteine


Question 9# Print Question

Which of the following statements about a 99mTechnetium-labelled dimercaptosuccinic acid (99mTc-DMSA) renogram is correct?

A. 10% of 99mTc-DMSA is taken up by active proximal convoluted tubular cells
B. 90% of 99mTc-DMSA is excreted in the urine by tubular secretion
C. One-third of the injected 99mTc-DMSA radioisotope is renal bound within one hour
D. Is significantly more accurate than a 99mTc-MAG-3 renogram for assessing differential renal function
E. 99mTc-DMSA renograms in adults deliver a total effective radiation dose of 0.3 mSv


Question 10# Print Question

Which of the following statements about bone scans performed to detect metastatic malignancy is correct?

A. 99mTechnetium-labelled methylene diphosphonate (99mTc-MDP) has high skeletal affinity and poor blood clearance
B. Images are obtained at 60 minutes following intravenous injection of the radioisotope
C. Patients are asked not to void prior to imaging
D. False negatives results may occur in metastatic deposits of aggressive anaplastic tumours
E. Bone scans help detect metastatic bone deposits by the increased osteoclastic activity they induce
