This study compared three rapid T2-weighted MR imaging pulse sequences (HASTE, turboGRASE, and rapid turbo SE) against high-resolution turbo spin-echo MR imaging in 18 patients referred for suspected uterine leiomyoma or adenomyosis. Using non-breath-hold, fat-saturated sagittal pelvic imaging on a 1.5 T system, acquisition times ranged from 17 seconds (HASTE) to 42 seconds (turbo SE), and images were evaluated in a blinded fashion for image quality and for detection/localization of leiomyoma and diagnosis of adenomyosis. The authors found no significant differences among the rapid sequences in diagnostic information, image quality, or performance for leiomyoma or adenomyosis, with HASTE showing the least ghosting. This paper is centrally about adenomyosis—rapid T2-weighted MR imaging methods for diagnosing adenomyosis alongside leiomyoma.

Abstract

BACKGROUND: To compare three rapid T2-weighted pulse sequences with high-resolution turbo spin-echo (SE) magnetic resonance (MR) imaging for the diagnosis of leiomyoma and adenomyosis. METHODS: Eighteen patients referred for evaluation of suspected leiomyoma or adenomyosis underwent imaging at 1.5 T with a phased-array multicoil. Non-breath-hold, fat-saturated sagittal images of 4-7 mm, with equivalent voxel size, were obtained through the pelvis with the following three rapid pulse sequences: segmented, half-Fourier single shot turbo SE (HASTE), turboGRASE (TGSE) and turbo SE MR images. Mean acquisition times were 17 s (HASTE), 37 s (TGSE), and 42 s (turbo SE). These images were compared, in a blinded fashion, to high resolution turbo SE MR images, which are considered the "standard" for pelvic MRI. RESULTS: The three rapid pulse sequences, HASTE, TGSE and turbo SE, provided equivalent diagnostic information when compared with high-resolution turbo SE MR images. There was no significant difference in image quality, detection and localization of leiomyoma or in diagnosis of adenomyosis among the three rapid sequences. HASTE imaging demonstrated the least ghosting. CONCLUSION: Diagnostic T2-weighted images of benign uterine pathology may be obtained in as little as 17 s.

Background

To compare three rapid T2-weighted pulse sequences with high-resolution turbo spin-echo (SE) magnetic resonance (MR) imaging for the diagnosis of leiomyoma and adenomyosis.

Methods

Eighteen patients referred for evaluation of suspected leiomyoma or adenomyosis underwent imaging at 1.5 T with a phased-array multicoil. Non-breath-hold, fat-saturated sagittal images of 4–7 mm, with equivalent voxel size, were obtained through the pelvis with the following three rapid pulse sequences: segmented, half-Fourier single shot turbo SE (HASTE), turboGRASE (TGSE) and turbo SE MR images. Mean acquisition times were 17 s (HASTE), 37 s (TGSE), and 42 s (turbo SE). These images were compared, in a blinded fashion, to high resolution turbo SE MR images, which are considered the ``standard'' for pelvic MRI.

Results

The three rapid pulse sequences, HASTE, TGSE and turbo SE, provided equivalent diagnostic information when compared with high-resolution turbo SE MR images. There was no significant difference in image quality, detection and localization of leiomyoma or in diagnosis of adenomyosis among the three rapid sequences. HASTE imaging demonstrated the least ghosting.

Conclusion

Diagnostic T2-weighted images of benign uterine pathology may be obtained in as little as 17 s.
