Hysterosalpingoscintigraphy in Diagnosing Infertility

Comparison with Other Diagnostic Methods

HSG remains the more common first-line test for evaluating tubal patency with 65% sensitivity and 85% specificity compared to laparoscopy, according to the American College of Radiology 1
HSG provides structural information about tubal patency, size, irregularity, and peritubal disease, but not functional transport capability, as noted by the American College of Radiology 1
MRI has high accuracy (75.6%) for detecting hydrosalpinges but is not typically used as a first-line test for tubal patency, as reported by the American College of Radiology 2

HSS is less commonly used than HSG or HyCoSy in routine infertility workups, as stated by the American College of Radiology 1
While HSS evaluates transport function, it does not provide detailed anatomical information about uterine abnormalities that might be detected with HSG, MRI, or hysteroscopy, according to the Journal of the American College of Radiology 3 and 4
