Women's Imaging MCQs

Mammography is primarily a screening and not a diagnostic tool. The mediolateral oblique (MLO) and craniocaudal (CC) views are standard screening views, whereas additional views described used mainly for diagnostic evaluation of lesions.

This scan is done for detection of Chromosomal markers & major structural anomalies in aneuploidies. Nuchal Translucency :Translucency between the skin and soft tissues posterior to the cervical spine Measuring Nuchal translucency When CRL is between 36 and 80mm. (10.3 – 13.6wks). In true sagittal section. With maximum magnification – 75% of the screen should be covered. (caliper 0.1mm). Neutral position- neither extension, nor flexion of the head.Mean of three values Reference: Ultrasound in obstetrics and gynecology by Dr. P.

In the first trimester, the focus of Doppler US is (a) detection of aneuploidy and an increased risk for congenital heart disease with evaluation of the ductus venosus waveform, and (b) screening for women more likely to develop preeclampsia by evaluation of the uterine artery waveform.

A double-layer thickness of less than 5 mm without focal thickening excludes significant disease and is consistent with atrophy. Homogeneous, smooth endometrium measuring 5 mm or less are considered within the normal range with or without hormonal replacement therapy Reference: Imaging the Endometrium: Disease and Normal Variants Kenneth M.

The breast within a breast appearence refers to the mammographic appearance of breast hamartomas (fibroadenolipomas). These benign lesions are well-circumscribed and as the name goes fibro-adeno-lipomas contain a mixture of fibrous, glandular and fatty tissue resembling a normal breast which also has fibroglandular and fatty tissue.
