[Novel Application of Post-contrast Tmap for Detection of Subendocardial Infarction].

In cardiac magnetic resonance (CMR) for myocardial infarction, there have been quite a few cases of obscure image contrast between subendocardial lesion and left ventricular (LV) blood pool on late gadolinium enhancement (LGE) images. This study was motivated by confirmation of usefulness of post-contrast Tmap for detection of subendocardial infarction. From June 2017 to May 2018, forty-eight consecutive patients who underwent contrast-enhanced CMR to assess myocardial infarction were reviewed.

Clinical significance of gadobutrol in magnetic resonance imaging for the detection of myocardial infarction: matched-pair cohort study to compare with gadopentetate dimeglumine at standard dose.

We aimed to confirm whether gadobutrol is more useful for late gadolinium enhancement (LGE) imaging than gadopentetate dimeglumine (Gd-DTPA) at the standard dose. Patients who underwent LGE imaging to assess myocardial infarction were retrospectively enrolled: gadobutrol, 51 cases; Gd-DTPA, 49 cases. Contrast ratios of infarcted lesion to remote myocardium (CR) and to left ventricular blood (CR) were compared.

[Clinical Usefulness of Ultra-short TE MRA for Follow-up Imaging after Cerebral Aneurysm Clipping].

The aims of this study were to elucidate signal pattern of cerebral aneurysm clip in brain magnetic resonance angiography (MRA) using non-contrast enhanced ultra-short echo time (UTE) sequence and to explore effective utilization of this novel technique for patients, who underwent cerebral aneurysm clipping. The clip was embedded in homemade phantom and scanned using UTE sequence. We investigated characteristic features of the artifacts derived from the clip.
