Magnetic resonance vasography using paramagnetic contrast agent - a case report

Azoospermia is recognised in 10-15% of men diagnosed due to infertility. Obstructive azoospermia occurs in 20-40% in this group of patients and it is characterised by normal FSH values, testes of normal size, and epididymal enlargement. Obstructive azoospermia is a common cause of male infertility. Several imaging techniques are used to assess the patency of the seminal tract, including the following: scrotal ultrasound, transrectal ultrasound (TRUS), and scrotal magnetic resonance imaging (MRI), with vasography being considered a gold standard. However, each of these methods has its limitations, and no single test can provide a comprehensive diagnosis. This article describes an attempt to combine high-resolution multiplanar MRI with functional evaluation of the patency of the seminal tract of classical vasography. A detailed description of the level of spermatic duct obstruction may help decide whether the condition qualifies for surgical treatment.
