Q1 · Iodinated Contrast
NEET PGMediumExplanation
Iodinated contrast can cause contrast-induced nephropathy, so renal function must be checked and caution taken in renal impairment, with hydration and dose adjustment. Previous severe contrast reaction and uncontrolled thyrotoxicosis are other cautions.
Q2 · Gadolinium
HardExplanation
Gadolinium contrast in severe renal impairment is associated with nephrogenic systemic fibrosis, a rare but serious fibrosing condition. Renal function should be assessed, and the safest agents and lowest doses used when contrast is necessary.
Q3 · Metformin and Contrast
HardExplanation
In renal impairment, iodinated contrast can reduce renal clearance of metformin, raising the risk of lactic acidosis. Guidelines advise assessing renal function and, in at-risk patients, withholding metformin around the time of contrast administration.
Q4 · Barium Contraindication
NEET PGMediumExplanation
If perforation is suspected, barium is avoided because leakage into the peritoneal cavity causes severe chemical peritonitis. A water-soluble iodinated contrast such as gastrografin is used instead, as it is resorbed safely.
Q5 · Imaging in Pregnancy
MediumExplanation
Ultrasound is first-line in pregnancy as it uses no ionising radiation; MRI, generally without gadolinium, is a further option. Ionising-radiation studies such as CT, fluoroscopy, and nuclear medicine are used only when the benefit clearly outweighs the risk.
Contrast Media and Safety sits within Radiology, which carries the same syllabus in both exams. This set runs to 5 questions, each tagged Easy, Medium or Hard, 2 of them at Hard, and 2 drawn from previous-year papers.
Answer first, then read the explanation even on the ones you got right — the reasoning is where Contrast Media and Safety marks are actually won, and it is what separates a recalled fact from a question you can solve in a new form. Once the Easy set feels comfortable, filter to Hard to find the gaps Radiology examiners keep returning to.
