We attempted to apply the optoelectronic sensor entitled 'OPT101' in intensive care unit clinics, based on its optoelectronic response characteristics in near-infrared wavelength range and near-infrared spectroscopy principle. The successful novel applications in our lab include earlydiagnosis and therapeutic effect tracking of thrombus, noninvasive monitoring of patients' shock severity, and f...

Noninvasive intermittent blood pressure monitoring was first developed 30 years ago.' It is now evolving from its former role as a somewhat esoteric research tool to becoming a clinically useful procedure for the evaluation ofhypertensive patients. In this review we outline its historical development, compare noninvasive 24-hour ambulatory blood pressure monitoring with the other available meth...

Stem cell-based cellular cardiomyoplasty represents a promising therapy for myocardial infarction. Noninvasive imaging techniques would allow the evaluation of survival, migration, and differentiation status of implanted stem cells in the same subject over time. This review describes methods for cell visualization using several corresponding noninvasive imaging modalities, including magnetic re...

We report two patients with a history of prior mitral valve and aortic valve replacement with St. Jude prosthetic valves, who were referred for repeat valve replacement after noninvasive assessment was suggestive of prosthetic valve malfunction. Both patients were managed medically after evaluation with direct left ventricular apical puncture revealed normal hemodynamics in the first and mild a...

Objective: Image evaluation after stent-assisted coil embolization (SAC) for a cerebral aneurysm is difficult with conventional MRA or CTA because of metal artifacts. Pointwise encoding time reduction radial acquisition (PETRA)-MRA noninvasive imaging examination that can reduce This study aimed to examine whether PETRA-MRA be used as follow-up SAC.

Coronary heart disease (CAD) is the leading cause of death specially among elderly. Coronary angiography is the best diagnostic method in the patients, but is unfortunately an invasive procedure with its inherent risks. Myocardial perfusion scan is a noninvasive and sensitive method for evaluation of CAD and is suggested by many investigators in recent years. In this study, 64 patients wh...
