[Assesment of lower extremities ischemic disease by thallium 201 perfusion scintigraphy in patients with diabetic angiopathy].
BACKGROUND/AIM Tibial perfusion in diabetic microangiopathy is considered to be a diagnostic problem. A special place in quantifying muscle microcirculatory perfusion belongs to thallium 201 muscle perfusion scintigraphy (201T1 PS). Thallium, showing the characteristics of potassium (K+), enters a cell by means of active cell transportation and follows erythrocyte up to the tissue. The aim of t...
متن کاملThallium-201 scintigraphy in unstable angina pectoris.
Thallium-201 scintigraphy was performed during the pain free period in 98 patients with unstable angina. Scintiscans were positive in 39 patients, questionable in 27 patients and normal in 32 patients. Eighty-one patients responded favorably to treatment (group I). Seventeen patients had complicated courses (group II) and despite maximal treatment with propranolol either developed infarction (s...
متن کاملDiagnosis of segmental necrosis in a pancreas transplant by thallium-201 perfusion scintigraphy.
Thallium-201 was used to image a patient with a pancreatic transplant. Incomplete visualization of the graft on the 201Tl scan, compared to CT, led to the diagnosis of segmental necrosis of the tail of the graft. Due to the low background and favorable target-to-non-target ratio, 201Tl pancreas scintigraphy may be useful in the follow-up of pancreatic transplants.
متن کاملThallium-201 Myocardial Perfusion Imaging
The sensitivity of myocardial perfusion imaging (MPI) using thallium-201 injected both at rest and during peak exercise was compared to simultaneously recorded 12 lead electrocardiography (ECG) for the detection of transient ischemia in 20 normal subjects and 63 patients with coronary artery disease (CAD). No significant perfusion defects or ECG changes were seen on either the rest or exercise ...
متن کاملCoronary Artery Disease Variability of Myocardial Perfusion Defects Assessed by Thallium-201 Scintigraphy in Patients With Coronary Artery Disease Not Amenable to Angioplasty or Bypass Surgery
OBJECTIVES We sought to assess the variability of results obtained with thallium scintigraphy as a method for tracking the extent of myocardial ischemia in medically refractory patients with angina who are not suitable for coronary artery bypass graft surgery or percutaneous transluminal coronary angioplasty. BACKGROUND New therapies are being evaluated for patients with “no option” angina in w...
