✦ Synopsis

In order to reduce the aquisition time, we compared the single-shot-TSE-MR myelography (MRm) and 3D-TSE-MRm. The T2-TSE sequence was the standard of reference. Fifty patients with low back pain, sciatica or cervical radiculopathy were examined at 1.0 T. The shortest AP diameter of the spinal canal, signal-to-noise ratio (SNR) for CSF and cord, contrast-to-noise ratio (CNR) and relative contrast (ReCon) between CSF and cord were calculated. No statistically significant difference was found between the three sequences with regard to the AP diameter of the spinal canal. A significant difference was found in: (i) SNRcord; (ii) SNRCSF; (iii) SS-TSE-MRm (showed the highest CNR) and (iv) SS-TSE-MRm (showed higher ReCon compared to 3D-TSE-MRm). In conclusion, SS-TSE-MRm can be used alternatively to 3D-TSE-MRm reducing the aquisition time down to only 8 s per image.

In 22 patients with a diverse range of thoracic abnormalities, T2-weighted magnetic resonance (MR) images of the chest were obtained with electrocardiograph (ECG)-triggered turbo spin-echo (TSE), ECG-triggered conventional spin-echo (CSE), and nontriggered TSE sequences, and the images were compared

So that we might evaluate the ultrafast half-Fourier single-shot turbo spin-echo (HASTE) sequence in T2-weighted MRI of the female pelvis and compare it with the turbo spin-echo (TSE) sequence, we prospectively studied 60 consecutive females with suspected abnormalities of the pelvis. For all MR exa
