Which of the following patient conditions would prohibit the IV administration of iodinated contrast medium? A previous severe contrast medium reaction The presence of severe renal failure Glaucoma Diabetics(IDDM) using insulin preparations
A previous severe contrast medium reaction The presence of severe renal failure Correct, but can be done if the patient is on active dialysis.

A single PA chest film delivers a dose of 0.02mSv A lumbar spine x-ray is equivalent to 100 chest x-rays A CT pneumocolon is equivalent to 500 chest x-rays A barium enema is equivalent to 360 chest x-rays
Complications of angiography include (select as many as you think): Thrombosis Haemorrhage Formation of pseudoaneurysms Arterial dissection Embolization
Thrombosis Haemorrhage Formation of pseudoaneurysms Arterial dissection Embolization That is correct. All of the answers are true.
MRI cannot be safely undertaken in which of the following conditions (choose 3 answers): Skin Tattoos in field of view Cerebral aneurysm clips Bilateral total hip replacement Cochlear implant In women with breast implants In patients with pacemakers
Cerebral aneurysm clips Cochlear implant In patients with pacemakers
Which statements below are true regarding pregnancy and imaging? Choose 2 answers. The period between fertilisation and implantation is the most sensitive to radiation Pelvic CT is contra indicated if early pregnancy is a possibility Lung scan for possible acute PE is contra indicated in pregnancy If a chest X-ray is inadvertently performed during early pregnancy abortion of the foetus should be considered Pregnant staff should avoid prolonged close contact with patients following bone scan injection
Pelvic CT is contra indicated if early pregnancy is a possibility Pregnant staff should avoid prolonged close contact with patients following bone scan injection
Ultrasound is the imaging modality of choice for which of the following suspected clinical conditions (choose 3 answers): Deep vein thrombosis Large bowel perforation Hydronephrosis Appendicitis Oesophageal reflux
Deep vein thrombosis Hydronephrosis Appendicitis
What is the abnormality on the chest x-ray?
Free intraperitoneal air
Heart Failure
Pneumothorax
Lung mass
Free intraperitoneal air
Free air under the hemi-diaphragm -This indicates perforation of intra-peritoneal bowel
Look at the image. This elderly ward patient has suddenly become sweaty and very breathless, what is the diagnosis?
Left ventricular failure
Pulmonary fibrosis
Left lower collapse
Pneumothorax
Left ventricular failure:
Large heart
Peri hilar haziness
Upper lobe blood diversion
Kerley B lines
This man has vomiting, constipation and abdominal pain- what is the diagnosis?
Large bowel obstruction
Small bowel obstruction
Large bowel obstruction:
Bowel cancer
Inflammatory mass, eg diverticulitis
Volvulus
You have been called to see a breathless young man in A&E. What is the diagnosis?
Left pleural effusion
Left Tension pneumothorax
Right middle lobe collapse
Left Tension pneumothorax
Hyperlucent left hemithorax with no lung markings indicates pneumothorax
Mediastinum shifted to the right, therefore tension pneumothorax
Treatment: insert chest drain/cannula urgently
How would you describe the hila on the CXR on the right?
Bilateral Hila enlargement
Right pneumothorax
Left upper lobe collapse
Bilateral Hila enlargement
This patient has bilateral hila lymphadenopathy seconday to lymphoma
Other causes include:
Vascular, e.g. pulmonary hypertension
Lymph nodes, e.g. metastases, sarcoid, TB
Main bronchi, e.g. lung cancer
Match the causes to the images:
Right lower lobe consolidation
Right pleural effusion
A = Effusion
B = Consolidation
