Cerebral blood flow and metabolism associated with cerebral microbleeds in small vessel disease
Cerebral microbleeds (CMBs), probably reflecting microangiopathy, have not yet sufficiently been examined in association with cerebral blood flow (CBF) and metabolism. We investigated the relationships between...

Quantification of myocardial blood flow using 201Tl SPECT and population-based input function
Thallium-201 (201Tl) single photon emission computed tomography (SPECT) is an important tool in the diagnosis of ischemic heart disease. Absolute quantification of myocardial blood flow (MBF) has the potential to...
