T2-weighted imaging
Also known as: T2WI
Taxonomy: Technique Branch / Method. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
The study aimed to evaluate the accuracy of T2-weighted imaging (T2WI)... On T2WI, the lesions appeared hypointense in 46 (92%) of the 50 cases. The findings of this study confirm the high accuracy of T2WI in diagnosing malignant prostate lesions.
Usefulness & Problems
Why this is useful
T2-weighted imaging is evaluated as a prostate MRI sequence for identifying malignant lesion signal characteristics. In this cohort, most lesions were described as hypointense on T2WI.; diagnosing malignant prostate lesions; lesion characterization within prostate MRI

Published Workflows
Objective: Evaluate the role and accuracy of biparametric MRI in patients with prostate cancer for diagnosis, extent assessment, and post-treatment early recurrence monitoring.
Why it works: The study evaluates MRI sequence findings in lesions that were later pathologically confirmed as prostate cancer, using pathology as the reference to assess how often specific MRI features are present in malignant lesions.

It requires MRI-based prostate imaging and image interpretation. The study evaluates T2WI against pathology-confirmed prostate cancer cases.; requires MRI acquisition as part of prostate imaging
The abstract does not show whether T2WI alone is sufficient for full clinical decision-making or how it compares quantitatively with other MRI protocols. It also does not provide false-positive or false-negative rates.; abstract reports lesion appearance frequency rather than full diagnostic performance metrics
