Imaging techniques used in Uterus anomalies EXCEPT: 
Select and explain. 
A. HSG, B. MRI guided HSG, C. CT guided HSG, D. USG
C: CT guided HSG
Answer: C: CT guided HSG 
Explanation: * Imaging studies, such as a hysterosalpingogram (HSG) and ultrasound, or an MRI are required to visualise the uterus and confirm that a congenital uterine anomaly is present. * A hysterosalpingogram is not considered as useful due to the inability of the technique to evaluate the exterior contour of the uterus and distinguish between a bicornuate and septate uterus. * In addition,laparoscopy and/orhysteroscopy may be indicated.
