Transverse testicular ectopia (TTE) is a rare congenital anomaly, in which both gonads migrate toward the same hemiscrotum with increased risk of testicular malignancy and associated with various abnormalities. Proper knowledge and imaging techniques are essential in diagnosis. Ultrasonography(USG) offer an easy, safe, and convenient alternative in assessment of TTE. We report a case of 41-year-male with infertility, who presented with left reducible inguinal hernia and right undescended testis. Final diagnosis was confirmed by USG and magnetic resonance imaging(MRI). The embryology, imaging features and USG evaluation of infertility are discussed with review of pertinent literature.
This study compared the image quality of single-shot echo-planar imaging (ss-EPI) and readout-segmented echo-planar imaging (rs-EPI) in cervical cancer (CC). ADC values derived from these two sequences were considered as diagnostic capabilities for CC’s lymph-vascular space invasion (LVSI) and lymph node metastasis (LNM). The results showed that rs-EPI images of cervical cancer had higher subjective image quality scores, lower SNR, but no difference in CNR and ADC values. ADC was able to predict the CC’s LNM status,but couldn’t identify the LVSI status. ADC of rs-EPI sequence was superior to diagnose CC’s LNM status.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
