What is the diagnostic study of choice for detecting testicular carcinoma?

CT scan of the abdomen
Blood tests for tumor markers
Scrotal ultrasound
X-ray of the pelvis

The correct answer is: Scrotal ultrasound

Scrotal ultrasound is the diagnostic study of choice for detecting testicular carcinoma because it provides excellent visualization of the testicular anatomy and is highly sensitive in identifying masses or abnormalities within the testes. An ultrasound can help distinguish between solid tumors and other conditions, such as hydrocele or varicocele, and can assess the structure of the testis in detail. Since testicular carcinoma often presents as a solid mass, this imaging modality is particularly effective in identifying these changes. While blood tests for tumor markers can be helpful in diagnosing or monitoring the disease, they are not used as a primary diagnostic tool. CT scans and X-rays are less preferred; a CT scan of the abdomen may be used later to evaluate for metastasis rather than to establish the diagnosis of testicular cancer, and X-rays of the pelvis are not specific to testicular conditions.
