The sternalis muscle is common, occurring in 80% of people. B. The sternalis muscle is only found unilaterally. C. The sternalis muscle is only found in Chinese people. D. The function of the sternalis muscle is uncertain. 3. Which one of the following statements is false? A. Interpretation of mammograms can be challenging. B. The sternalis muscle is seen as an irregular calcified mass on mammography. C. The sternalis muscle is seen on occasion on the cranio-caudal view of the mam- mogram. D. The sternalis muscle is found in all population groups. 5. With regard to mammography, which one of the following statements is incorrect? A. Subtle signs of breast cancer can be missed by radiologists. B. Computer-aided diagnosis (CAD) was developed to draw the radiologists attention to suspicious regions in a mammogram. C. Commercial CAD systems are designed to be consulted before the radiologist has made an initial assessment. D. One aspect of the CAD system is to detect suspicious features. 6.

Breast cancer is the most common cancer among women worldwide. C. Breast cancer is second to cervical cancer among South African women. D.

Identify one false statement below: A. 50% of patients with t large PDA will devel- op pulmonary hypertension. B. Patients with a large PDA left patent may develop Eisenmenger’s syndrome. C. Eisenmenger’s syndrome is an irreversible condition where there is a reversal of flow of a congenital systemic to pulmonary shunt that occurs in untreated congenital heart defects. D. Untreated Eisenmenger’s syndrome in turn can develop into the classic Hippocratic syndrome. 9. Concerning chest radiographs most suggestive of PDA, which one of the statements below is incorrect? A. Filling in of the aorto-pulmonary window and enlargement of the pulmonary arteries. B. Pruning of pulmonary arteries peripherally. C. Calcification of the left ventricle. D. Calcification of the PDA in elderly patients. 10. Which one of the following is correct? A. In detecting PDA trans-thoracic echocar- diogram is superior to trans-oesophageal echocardiogram. B. Trans-oesophageal echocardiograms are used much more commonly in diagnosing PDAs. C. CT angiography and magnetic resonance angiography have largely replaced formal angiography in the investigation of PDAs. D. PDAs complicated by Eisenmenger’s syn- drome are very easy to detect on transtho- racic echocardiography. 4. Identify one correct statement among the following.
