Imaging of uterus anomalies can be conducted using various techniques, but each serves a specific purpose and application. Let's analyze the given options:
- HSG (Hysterosalpingography): An X-ray technique that checks for blockages in the fallopian tubes and uterine irregularities. Primarily used in infertility investigations.
- MRI guided HSG: Utilizes MRI to enhance the assessment of uterine anomalies, benefiting from the superior soft tissue contrast capability of MRI.
- CT guided HSG: This option is not commonly used as CT does not provide optimal soft tissue differentiation necessary for evaluating uterine anomalies, and it involves unnecessary radiation exposure.
- USG (Ultrasound): A non-invasive technique widely used to evaluate pelvic structures, including the uterus, with real-time imaging.
The correct answer to the question about imaging techniques excepted for uterus anomalies is CT guided HSG, as it is not a standard method for imaging uterine anomalies due to the disadvantages mentioned.
