"MRI is occasionally used for problem solving if the diagnosis is unclear on ultrasound. CT is only rarely needed, and is avoided because of its ionising radiation. Nuclear medicine studies (e.g. Tc99m-pertechnetate) have also fallen out of favour because of their ionising radiation."

"adult diameter measures between 3-5 cm, with a volume of ~20 mL"
"normal scrotal skin thickness varies between 2-8 mm 5"
"the tunica (vaginalis/albuginea) appears as an echogenic outline of the testis:"
"the tunica invaginates to form the linear echogenic testicular mediastinum (a.k.a. mediastinum testis)"
"the rete testis can be identified in ~20% of patients"
"if a scrotal mass is found, one of the primary roles of ultrasound is to determine if it is intratesticular or extratesticular"

"important: both a short axis greyscale and a colour Doppler image should be obtained, in which both testes are imaged side-by-side ("buddy shot" or "sunglasses view"), to compare the size, relative echogenicity and blood flow"
