Sample item

Which MRI sequence is most sensitive to blood products and susceptibility effects?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Gradient-echo or susceptibility-weighted imaging

Gradient-echo and susceptibility-weighted sequences accentuate magnetic susceptibility from blood products, calcification, and some metal deposits.

Option by option

  • A. Gradient-echo or susceptibility-weighted imaging (correct)

    Correct: susceptibility sequences detect paramagnetic blood products.

  • B. MR cholangiography only

    MRCP is a biliary protocol.

  • C. T2 FLAIR only

    FLAIR suppresses CSF rather than maximizing susceptibility.

  • D. T1 inversion recovery only

    T1 imaging is less sensitive to microbleeds.

Questions about this Radiology question

What is the answer to this Radiology question?

The best answer is A, Gradient-echo or susceptibility-weighted imaging. Gradient-echo and susceptibility-weighted sequences accentuate magnetic susceptibility from blood products, calcification, and some metal deposits.

Why is "MR cholangiography only" not the answer?

MRCP is a biliary protocol.

Why is "T2 FLAIR only" not the answer?

FLAIR suppresses CSF rather than maximizing susceptibility.

Why is "T1 inversion recovery only" not the answer?

T1 imaging is less sensitive to microbleeds.

What concept does this question test?

It tests MRI physics in Radiology. The correct option holds because: Correct: susceptibility sequences detect paramagnetic blood products.

How hard is this question?

We tag it as an application question: it asks you to use a fact on a patient or a finding. The tag is our own editorial judgement, not an official difficulty rating, so read the reason for every option, not only the answer.

How should I study MRI physics?

Learn signs with the image, and the disease they point to. Then use the flashcards and the other Radiology questions on this site to test what stuck.

Is this a real NEET PG question?

No. It is an original practice item (editorial status: sample, version 1). NextPrep does not publish recalled or leaked questions, and independent faculty review of this item has not been completed yet, so confirm important facts in a standard textbook.
