The need for speed - adenosine stress MRI in less than 30 minutes
Background Strong evidence in favour of an ischaemia-guided approach to coronary revascularisation for PCI has led to a huge increase in demand for ischaemia imaging. In our General Hospital setting we have seen a 300% increase in demand for stress MRI over 3 years to more than 800 examinations per year. We therefore sought to optimise patient throughput by process mapping and by the introducti...
متن کاملTMS brain mapping in less than two minutes.
BACKGROUND Transcranial magnetic stimulation (TMS) corticospinal excitability maps are a valuable tool to study plasticity in the corticospinal tract. Traditionally, data acquisition for a single map is time consuming, limiting the method's applicability when excitability changes quickly, such as during motor learning, and in clinical investigations where assessment time is a limiting factor. ...
متن کاملSerum calcitonin negative Medullary thyroid carcinoma
BACKGROUND Medullary thyroid carcinomas (MTC) constitute about 5 to 7% of thyroid neoplasms. They originate from parafollicular C cells which produce Calcitonin, a hormone which has an impact on calcium metabolism and represents the biochemical activity of MTC. In rare cases pre-operative serum calcitonin can be negative. CASE PRESENTATION We report on a 73-year-old female patient with a rare...
متن کاملAssessment of coronary arteries with total study time of less than 30 minutes by using whole-heart coronary MR angiography.
This study had institutional review board approval, and all patients gave informed consent. The purpose of this study was to prospectively evaluate the use of whole-heart three-dimensional (3D) coronary magnetic resonance (MR) angiography in patients suspected of having coronary artery disease. Whole-heart coronary MR angiography was performed in 39 patients (30 men and nine women; mean age, 63...
متن کاملTotal and free thyroid hormone concentrations after elective surgery.
Changes in thyroid hormone concentration and distribution and plasma cortisol levels have been followed in 11 patients undergoing elective cholocystectomy. A significant rise in total and free thyroxine (T4) and fall in total and free triiodothyronine (T3) were noted after surgery. Reverse T3 concentrations rose substantially, suggesting that peripheral conversion of T4 to T3 is diminished and ...
