Thirty questions on the cardiac imaging modalities, and the thread running through them is which study answers which question. Chest radiography is rarely the study you order and often the study you already have. Ultrasound shows anatomy and flow with no radiation but depends entirely on the operator. Echocardiography is the functional study; computed tomography is the anatomical one and explicitly cannot assess function. Nuclear perfusion imaging answers a question none of the others can — whether muscle is alive — and magnetic resonance avoids both radiation and iodinated contrast. Angiography is the gold standard, and the only one that can treat what it finds. You are not asked to recall a threshold or to calculate anything. The two figures that matter — the cardiothoracic ratio and the 85 percent of predicted maximum heart rate that makes a stress test valid — are supplied in the stem, and the question is what follows from them. A ratio you can recite but not apply to a film is worth nothing. Built from the slides. The recording for this lecture is queued behind the exams that come sooner, so every question cites the slide it came from and spoken emphasis will be layered in once the transcript lands.
