PURPOSE To characterize perfusion patterns of periictal single-photon emission tomography (SPECT) in patients with unilateral temporal lobe epilepsy (TLE) and to determine their relationship to the epileptogenic zone (EZ). METHODS We studied periictal SPECT scans of 53 patients after anterior mesial temporal lobectomy who had good seizure outcome after surgery. Ictal SPECT scans were performed during video-EEG monitoring. Typical SPECT patterns consisted of ipsilateral ictal hyperperfusion or ipsilateral postictal hypoperfusion. Atypical ictal patterns included normal scans, bilateral temporal hyperperfusion, or contralateral patterns. These perfusion patterns were retrospectively analyzed searching for concordance rate with the EZ. RESULTS We obtained 51 ictal and two early postictal scans. In the typical group, 40 (75.4%) patients had ipsilateral ictal temporal lobe hyperperfusion, and one (1.9%) patient had ipsilateral postictal temporal lobe hypoperfusion. Twelve (22.7%) patients exhibited
*  Predictive value of brain perfusion single-photon emission computed tomography in acute ischemic stroke. | Stroke
We investigated 32 patients with completed ischemic stroke less than or equal to 6 hours after the onset of symptoms by means of computed tomography, cerebral angiography, and technetium-99m-labeled hexamethylpropyleneamine oxime single-photon emission computed tomography to study cerebral blood flow. Follow-up computed tomography and cerebral blood flow studies were performed 1 week and 1 month after admission. Poor outcome at 1 month was evident in 18 (78%) of the 23 patients with severe neurologic deficit on admission and in 11 (92%) of the 12 patients with severe hypoperfusion in the affected hemisphere on admission. All 10 patients with severe impairment of both neurologic status and cerebral blood flow had a poor outcome at 1 month. We detected severe hypoperfusion in patients with large lesions on computed tomograms or cerebral artery occlusions on angiograms. Cerebral blood flow had increased at the 1-week follow-up despite different clinical outcomes. Our data provide evidence that ...

Images obtained from a CTA will demonstrate absent blood flow beyond the extracranial internal carotid and vertebral arteries; the external carotid arteries and its branches should remain patent. Likewise, brain scintigraphy may also be performed to confirm the diagnosis. Technetium 99m-labeled hexamethylpropyleneaminoxime (99mTc-HMPAO) or 99mTc-labeled ethylene L-cysteinate dimer (99mTc-ECD) are two perfusion agents that made be used. As their names imply, these perfusion agents demonstrate uptake in perfused tissues. In the presence of cerebral demise, the dynamic and static images will demonstrate the absence of radiotracer above the skull base. The bolus of radiotracer will fail to perfuse the intracranial internal carotid and cerebral arteries. Relatively increased flow through the maxillary branch of the external carotid artery will cause relatively increased radiotracer accumulation in the nasal region, resulting in the "hot nose" sign, which is best seen on the anterior static images. ...
*  Comparison of Cardiac Computed Tomographic Angiography (CTA) to Tc-99m Single Photon Emission Computed Tomography (SPECT) -...
Cardiovascular disease and ischemic heart disease is the #1 killer in Canada. Currently, Cardiac invasive catheterization angiography (CICA) is the gold standard for the assessment of the arteries in the heart. However, cardiac catheterization has risks which prohibit its use in all patients. These risks include: death, heart attack, stroke and bleeding. Cardiac computed tomography angiography (CTA) is a new non-invasive technology which may enable the evaluation of patients' coronary anatomy without exposing patients to the risks of invasive cardiac catheterization.. The purpose of this project is to compare CT angiography (CTA) to Tc-99m single photon emission computed tomography (Tc-99m SPECT). We will enroll patients who are waiting for a CICA or who have been referred for a TC-99m SPECT or CTA scans at the University of Ottawa Heart Institute. Consenting patients who are waiting for a CICA will have both a CTA and a Tc-99m SPECT scan. Consenting patients referred for a CTA or Tc-99m SPECT ...

PURPOSE:. To evaluate the impact of brain MRI and single-photon emission computed tomography (SPECT) in early detection of central nervous system abnormalities in patients affected by Wilson's disease (WD) with or without neurological involvement.. METHODS:. Out of 25 consecutive WD patients, 13 showed hepatic involvement, ten hepatic and neurological manifestations, and twp hepatic, neurological, and psychiatric symptoms, including mainly movement disorders, major depression, and psychosis. Twenty-four healthy, age-gender matched subjects served as controls. All patients underwent brain MRI and (99m)Tc-ethyl-cysteinate dimer (ECD) SPECT before starting specific therapy. Voxel-by-voxel analyses were performed using statistical parametric mapping to compare differences in (99m)Tc-ECD brain uptake between the two groups.. RESULTS:. Brain MRI showed T2-weighted hyperintensities in seven patients (28%), six of whom were affected by hepatic and neurological forms. Brain perfusion SPECT showed ...

*  Viability is in the Eye of the Beholder… | JACC: Cardiovascular Imaging
The term myocardial "viability" in chronic left ventricular (LV) dysfunction due to coronary artery disease has been interpreted in multiple ways by clinicians and imagers alike. The classic definition assesses whether or not the myocardial tissue under consideration is alive or dead. However, more often we have used the term to address whether or not the tissue would recover function, especially after revascularization. The variability of imaging definitions of viability further adds to the problem. The imaging definition of viability depends upon the eye of the beholder. For example, an echocardiographer defines viability as a preserved contractile response to low doses of dobutamine (LDD) or inotropic reserve. Those performing single-photon emission computed tomography (SPECT) define viability by the absolute number of counts of myocardial perfusion tracers across a segment of myocardium, or by the demonstration of redistribution of radiotracer in the region of interest at rest. Positron ...
