Single best answer (SBA) questions have been introduced into the Final FRCR Part A examination of the Royal College of Radiologists in the UK for the first time. This book of 600 SBA questions and explanatory answers has been written to aid students preparing for the exam by current trainees in clinical radiology, coordinated through The Society of Radiologists in Training (SRT). Questions are grouped by topic and each topic is split into three papers of 70 questions, with explanations separated into chapters to enable readers to either attempt a whole mock exam paper or to browse question by question. The book is a bridge between a pure revision aid and a reference text, including a bibliography of useful references for further information. Candidates for other professional exams in Radiology will find the text useful, as will and those from other specialties wishing to explore the radiological aspects of their syllabus in greater depth. This is a companion volume to Final FRCR Part A Modules 4-6 Single Best Answer MCQs by the same team.

Cardiothoracic and vascular radiology

PAPER 1

1. 1 A 34-year-old female undergoing a contrast swallow is noted to have a smooth anterior indentation on the oesophagram. Which of the following is most likely to be responsible?
   1. a Right-sided aortic arch
   2. b Aortic aneurysm
   3. c Aberrant right subclavian artery
   4. d Aberrant left pulmonary artery
   5. e Double aortic arch

1. 2 A 34-year-old female presented with hypertension and an ejection systolic murmur. Which finding is most likely to support a diagnosis of true coarctation compared to pseudocoarctation?
   1. a Figure ‘3’ sign on angiogram
   2. b An associated bicuspid aortic valve
   3. c Rib notching
   4. d High positioned aortic arch
   5. e Dilatation of the distal aorta

1. 3 A 72-year-old man presented to his general practitioner with progressive dyspnoea. He has a history of hypertension and is a smoker. The chest radiograph demonstrates mild cardiomegaly and widening of the mediastinum at the level of the aortic arch. After referral to a cardiologist, a contrast-enhanced computed tomography examination was performed which revealed a soft tissue density mass in contact with the aortic arch with a central pool of contrast at the same density as the aorta. The pre-contrast images showed a fine rim of calcification peripherally. What is the most likely diagnosis?
   1. a Aortic dissection with mediastinal haematoma
   2. b Bronchogenic carcinoma invading the mediastinum
   3. c Bronchogenic cyst
   4. d Lymphadenopathy
   5. e Atherosclerotic aortic aneurysm

1. 4 A 50-year-old man who is an outpatient had a chest radiograph that demonstrates globular cardiomegaly suspicious of a pericardial effusion. What would be the next appropriate investigation to further investigate this finding?
   1. a Magnetic resonance imaging
   2. b Echocardiogram
   3. c Computed tomography examination
   4. d Electrocardiogram
   5. e Myocardial perfusion scan

1. 5 A 25-year-old female underwent a CT to investigate a history of progressive leg claudication, abdominal pain, night sweats and myalgia. Circumferential thickening of the thoracic and abdominal aortic wall with a stenosis in the thoracic aorta was seen and a magnetic resonance angiogram performed. On short tau inversion recovery (STIR) sequences there is high signal in the aortic wall. What is the most likely diagnosis?
   1. a Behcet’s disease
   2. b Acute lymphoblastic leukaemia
   3. c Polyarteritis nodosa
   4. d Takayasu’s arteritis
   5. e Giant cell aortitis

1. 6 A previously fit and well 45-year-old male presented with fever, abdominal pain and weight loss. Clinical examination was unremarkable. The erythrocyte sedimentation rate was raised but his leucocyte count was normal. After referral to the surgical team a CT of his abdomen was performed. This showed thickening of the wall of the ascending colon with pericolic fat stranding. Contrast was seen within the superior mesenteric vessel and there was a wedge-shaped area of low attenuation in the spleen. A selective angiogram of the superior mesenteric artery was performed, which demonstrated multiple aneurysms measuring between 1 and 5 mm. What is the most likely diagnosis?
   1. a Ischaemic colitis
   2. b Systemic lupus erythematosus
   3. c Polyarteritis nodosa
   4. d Rheumatoid vasculitis
   5. e Wegener’s granulomatosis

1. 7 A 39-year-old male smoker was referred to a cardiologist with chest pain. A cardiac magnetic resonance examination was requested as part of his work-up. This showed patchy multifocal delayed hyperenhancement within the basal interventricular septum. What is the most likely diagnosis?
   1. a Sarcoidosis
   2. b Amyloidosis
   3. c Ischaemic myocardium
   4. d Myocarditis
   5. e Hypertrophic cardiomyopathy

1. 8 A 25-year-old male was referred for a routine testicular screening ultrasound. He is known to have a cardiac myxoma and has multiple pigmented lesions on his face and lips. What is the most likely unifying diagnosis?
   1. a Carney’s syndrome
   2. b Peutz-Jeghers syndrome
   3. c Waardenburg’s syndrome
   4. d Cronkhite-Canada syndrome
   5. e Gorlin’s syndrome

1. 9 Regarding multidetector computed tomography for coronary artery disease, which of the following statements is true?
   1. a It has a low negative predictive value
   2. b It is ideally used in a population with a low pre-test probability of coronary artery disease
   3. c It is accurate in detecting stenosis in small vessels
   4. d The Rockford scoring system is used
   5. e It is less accurate than magnetic resonan...
