1. A chest radiograph of a 40-year-old patient shows straightening of the left heart border, a double density at the right heart border, and elevation of the left main bronchus. These findings together are most consistent with:
2. A 70-year-old hypertensive man undergoes CT angiography for back pain. The aorta shows concentric wall thickening with intimal calcification that remains attached to the outer aortic wall, and a crescent of high-density material within the aortic wall on non-contrast CT without an intimal flap. This is most consistent with:
3. On chest X-ray, which of the following features indicates LEFT atrial enlargement?
4. On CT angiography, which finding differentiates a Type A (DeBakey I/II) from a Type B (DeBakey III) aortic dissection?
5. On cardiac MRI, late gadolinium enhancement (LGE) in a patient with hypertrophic cardiomyopathy most commonly appears as:
6. On CTA of the aorta, 'intimal flap' separating true from false lumen is the defining feature of aortic dissection. The false lumen can be distinguished from the true lumen by which CT sign?
7. ECG-gated CT coronary angiography (CTCA) shows a plaque in the left anterior descending artery (LAD) with a CT attenuation of −40 HU within the plaque. This low-density plaque component indicates:
8. Transoesophageal echocardiography (TOE/TEE) and CT aortography are performed in a 65-year-old with acute chest pain and back pain. CT shows a dissection flap in the descending thoracic aorta starting at the left subclavian artery takeoff, with the false lumen extending to the iliac arteries. There is no involvement of the ascending aorta. According to the Stanford classification, this is:
9. On CT pulmonary angiography (CTPA), a 'saddle embolus' refers to a thrombus at which location?
10. On cardiac MRI, the technique of 'late gadolinium enhancement' (LGE) at 10–15 minutes post-contrast is used to identify myocardial fibrosis/scar. In ischemic cardiomyopathy, LGE is characteristically:
11. On CT pulmonary angiography (CTPA), which finding in the main pulmonary artery reliably indicates massive (central) pulmonary embolism with high haemodynamic risk?
12. On cardiac MRI, the LGE (late gadolinium enhancement) pattern in hypertrophic cardiomyopathy (HCM) is MOST commonly located at:
13. On a plain chest radiograph, which sign indicates a left-sided aortic arch with aberrant right subclavian artery (arteria lusoria)?
14. On chest X-ray, 'eggshell calcification' of hilar lymph nodes is most characteristic of which condition?
