Imaging Cellular Proliferation in Prostate Cancer with Positron Emission Tomography
Prostate cancer remains a major public health problem worldwide. Imaging plays an important role in the assessment of disease at all its clinical phases, including staging, restaging after definitive therapy, evaluation of therapy response, and prognostication. Positron emission tomography with a number of biologically targeted radiotracers has been demonstrated to have potential diagnostic and...
متن کاملQuantification of Absolute Myocardial Perfusion With Dynamic Positron Emission Tomography
Positron emission tomography (PET) was applied to the measurement of myocardial perfusion using the perfusion tracer 13N-labeled ammonia. 13N ammonia was delivered intravenously to 13 healthy volunteers both at rest and during supine bicycle exercise. Dynamic PET imaging was obtained in three cross-sectional planes for 10 minutes commencing with each injection. The left ventricle was divided in...
متن کاملThe effect of fasting on Positron Emission Tomography (PET) imaging
As a nuclear approach, Positron Emission Tomography (PET) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide. There are certain limitations to this technique such as normal tissue uptake. Therefore, it has been recommended that patients prepare before scanning. Fasting for a short while before PET imaging is an exampl...
متن کاملEvaluation of the Novel Myocardial Perfusion Positron-Emission Tomography Tracer
Background—Positron-emission tomography (PET) tracers for myocardial perfusion are commonly labeled with short-lived isotopes that limit their widespread clinical use. F-BMS-747158-02 (F-BMS) is a novel pyridaben derivative that was evaluated for assessment of myocardial perfusion by comparison with N-ammonia (NH3) and with radioactive microspheres in a pig model. Methods and Results—Fourteen p...
متن کاملPrognostic Value of Stress Myocardial Perfusion Positron Emission Tomography
Results Risk-adjusted hazard of cardiac death increased with each 10% myocardium abnormal with mildly, moderately, or severely abnormal stress PET (hazard ratio [HR]: 2.3 [95% CI: 1.4 to 3.8; p 0.001], HR: 4.2 [95% CI: 2.3 to 7.5; p 0.001], and HR: 4.9 [95% CI: 2.5 to 9.6; p 0.0001], respectively [normal MPI: referent]). Addition of percent myocardium ischemic and percent myocardium scarred to ...
