25. Preparation and evaluation of modified composition for lyophilized kits of [Cu(MIBI)4]BF4 for [99mTc] technetium labeling
Neste trabalho são apresentados dados relativos a síntese do complexo [Cu(MIBI)4]BF4 e à utilização do mesmo para produção de kit liofilizado para obtenção do radiofármaco [[99mTc](MIBI)6]+. No processo de síntese foi utilizado radiação de microondas como fonte de aquecimento em uma etapa do processo, permitindo que a reação fosse executada em

26. Cintilografia com MIBI-dipiridamol negativa em doença coronariana grave no pré-operatório de correção de aneurisma de aorta abdominal
Descreve-se o caso de um paciente de 73 anos, candidato à correção de aneurisma de aorta abdominal, sem anormalidades na primeira avaliação cardiológica. A cirurgia foi postergada para tratamento de epididimite. Duas semanas após, o paciente retornou ao hospital com dor torácica e a angiografia mostrou obstruções de duas coronárias, tratadas com s

27. ComparaÃÃo de dados cintilogrÃficos entre afixaÃÃo miocÃrdica do Sestamibi-Tc99m com a doTÃlio-201 no estudo do miocÃrdio hibernante
The aim of this study was to carry out a quantitative analysis in order to compare 99mTc-sestamibi (99mTc-MIBI) uptake at rest with that of Thallium-201 (201Tl) among patients with ejection fraction lower than 35%. Methods: twenty-eight patients (average age 63 Â 14 years) with ischemic cardiopathy, were submitted to scintigraphy with 201Tl and 99mTc-MIBI.

28. AvaliaÃÃo da influÃncia do percentual de marcaÃÃo do 99mTc-MIBI em procedimentos de medicina nuclear em Recife
The aim of this work was to evaluate the influence of percent labeling of the radiopharmaceutical 99mTc-MIBI on the procedures adopted by the nuclear medicine clinics in Recife, and their possible interference with image quality in myocadial perfusion examinations. This work was performed at two nuclear medicine services in Recife that use pharmaceuticals pr

30. Detecção e classificação automaticas de lesões em cintilografias de mama com NIBI-99mTe usando um filtro de novidade
Recent reports have shown 99mTc- MIBI uptake in malignant and benign breast lesions. These reports emphasize that mammography remains the procedure of choice in screening asymptomatic women for breast cancer. However, in patients with symptoms, the use of 99mTc- MIBI scintimammography offers a simple non-invasive method for the detection of breast cancer whi

31. Metodo automatico para construção de mapas polares
Bull s Eye , or polar map, is a semi-automatic method for the quantification of reiative myocardial perfusion defects from SPECT (Single Photon Emission Computed Tomography) tomograms obtained by labeling the myocardium with 201 IND. TI or MIBI POT. 99m Tc. The quantitative analysis of thallium and technetium studies is performed by comparing the Polar Map w

33. A new approach to parathyroidectomy.
OBJECTIVE: To decrease the operative time for parathyroidectomy in patients with hypercalcemic (primary) hyperparathyroid disease, a combination of preoperative localization of a parathyroid tumor with an effective nuclear scan (scintigram) and intraoperative monitoring of parathyroid hormone (quick parathyroid hormone measurement) to ensure excision of all

34. High incidence of scintigraphic myocardial uptake defects at rest and during exercise in male elite runners.
OBJECTIVE: To evaluate the usefulness of myocardial perfusion scintigraphy (MIBI-SPECT) as a diagnostic tool in well trained men. DESIGN: The study was prospective, involving 2 d stress-rest myocardial scintigraphy (MIBI-SPECT), polar map reconstruction with and without uniform attenuation correction, and comparison with a healthy male group (local Swedish)

35. Evaluation of changes in myocardial perfusion and function on exercise in patients with coronary artery disease by gated MIBI scintigraphy.
OBJECTIVE--To investigate the ability of gated methoxy-isobutylisonitrile (MIBI) scintigraphy to measure changes in myocardial function as well as perfusion with exercise. SETTING--Regional cardiothoracic centre. PATIENTS--43 presenting with chest pain, 28 with coronary artery disease on angiography, and 15 with normal coronary arteriograms. RESULTS--Gated p

36. Comparative ability of dobutamine and exercise stress in inducing myocardial ischaemia in active patients.
OBJECTIVE--To compare the ability of dobutamine and exercise stress to induce myocardial ischaemia and perfusion heterogeneity under routine clinical circumstances. DESIGN--86 active patients without previous myocardial infarction were studied by dobutamine and exercise stress protocols and coronary angiography. During both tests patients underwent electroca
