All of the following imaging techniques are used in uterine anomalies EXCEPT:
Show Hint
The radiation-heavy, poor soft-tissue option is the one not used.

- HSG
- MRI-guided HSG
- CT-guided HSG
- USG
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: This is an EXCEPT question, so the goal is to spot the modality that does NOT belong to the standard work-up of a congenital uterine anomaly.
Step 2: The accepted trio is ultrasound, hysterosalpingography and MRI. USG (often 3D) and MRI image the cavity and the external fundal contour, which is what differentiates septate from bicornuate uteri, while HSG defines the cavity and tubal patency. MRI-guided assessment also fits the soft-tissue strength of MRI.
Step 3: CT-guided HSG is the odd one out. CT uses ionising radiation and gives inferior soft-tissue resolution for the female pelvis, so it is not employed to characterise uterine anomalies. That makes it the exception.
\[\boxed{\text{CT-guided HSG}}\]
