METHODS: We retrospectively examined 47 patients presenting with an acute scrotum who underwent dynamic contrast-enhanced MRI. Time–signal intensity curves (TICs) were constructed from the contrast effect of the testis, and cases wherein a difference in blood flow was observed (average signal intensity ratio less than 0.5) were defined as those of a suspected testicular torsion. RESULTS: Among the 47 cases, the median age of the patients was 15 years; the affected side was the right in 15 cases and the left in 32 cases. The findings of contrast-enhanced MRI were testicular torsion (n=14), appendiceal torsion (n=1), epididymitis (n=15), varicocele (n=1), and nonspecific (reduced to normal enhancement, n=16). Surgery was performed in 13 of 14 cases with suspected torsion of the testis, all involved diagnoses of spermatic torsion, and conservative surgery was selected in all cases. Patients with appendiceal torsion received symptomatic therapy. Patients with epididymitis were treated with antibiotics, and no patients returned for visits due to worsening symptoms or relapse. In this study, the accuracies of dynamic contrast-enhanced MRI based on surgical findings and/or subsequent clinical outcomes were both 100%, respectively. CONCLUSIONS: Contrast-enhanced MRI provides information regarding blood flow of the testes, and it is thought that results with high objectivity and high accuracy can be obtained. MRI could be a valuable diagnostic tool to avoid unnecessary surgery.
