Professor Masako Kataoka's research lab specializes in clinical and diagnostic MRI applications, focusing on improving image quality and diagnostic accuracy in women's health and oncology. Her team investigates advanced MRI techniques for breast, pelvic, and renal imaging, with an emphasis on optimizing sequences for better tissue characterization and reducing scan time without compromising diagnostic value. Key research directions include high-resolution pelvic MRI for dysmenorrhea, kidney imaging with respiratory triggering, and efficient post-contrast imaging in head and neck tumors.
Figures are computed from collected data and may differ slightly.
BAC found on mammograms was associated with prevalent CHD after adjustment for age, but with low sensitivity. BAC may provide additional information toward identifying cardiovascular disease risk among otherwise healthy women.
DTI of kidneys with respiratory triggering is feasible with excellent cortex-medulla differentiation.
Our results suggest that MRI of the female pelvis at 3T may potentially provide excellent images of the uterine cervix on high-resolution T2WI. New techniques to reduce inhomogeneity are thus called for.

MR imaging features of the uterus on cycle days 1-3 correlated with pain degree. Cine-mode-display MR imaging is a potential tool for evaluating dysmenorrhea.
In preoperative evaluations of head and neck tumors, the postcontrast VIBE sequence is capable of decreasing acquisition time without degrading image quality or tumor conspicuity; thus, it is an acceptable alternative to postcontrast spin-echo T1-weighted imaging.
Ultrafast dynamic contrast-enhanced (UF-DCE) MRI is a new approach to capture kinetic information in the very early post-contrast period with high temporal resolution while keeping reasonable spatial resolution. The detailed timing and shape of the upslope in the time-intensity curve are analyzed. New kinetic parameters obtained from UF-DCE MRI are useful in differentiating malignant from benign lesions and in evaluating prognostic markers of the breast cancers. Clinically, UF-DCE MRI contribute
The fully automated software can be used to quantify uterine peristalsis comparable to visual evaluation.
Dielectric pads consisting of either US gel or water are effective in improving image homogeneity of the pelvis on 3T MRI.
