Technetium-99m-MIBI scintimammography by planar and SPECT imaging in the diagnosis of breast carcinoma and axillary lymph node involvement.

Background: We compared SPECT and planar (99m)Tc-MIBI scintimammography (SMM) in the detection of primary breast cancer and metastatic axillary lymph node involvement, and the scintigraphic results with the histopathological/cytological findings.

Material And Methods: 303 consecutive patients with 308 suspicious or indeterminate lesions observed in mammographies were entered in this study. After an intravenous injection of 740 MBq of (99m)Tc-MIBI, anterior supine, right and left lateral planar images in a prone position and a SPECT study were acquired.

Activity and practice of nuclear cardiology in the Czech Republic, 2001.

Radionuclide myocardial perfusion imaging (MPI) has been on the rise in Europe and the USA. Details on nuclear cardiology in the Czech Republic are not available as yet, as it is impossible to obtain comprehensive data from official registers owing to different methods of reporting and data evaluation. A questionnaire concerning nuclear cardiology activity and practice in 2001 was sent to all nuclear medicine departments in the Czech Republic.

Increased prognostic value of combined myocardial perfusion SPECT imaging and the quantification of lung Tl-201 uptake.

Purpose: The authors wanted to identify those patients assessed by exercise SPECT in whom the quantification of lung Tl-201 uptake helps to evaluate disease prognosis.

Methods: One hundred forty-nine patients (114 men, 35 women; 74 after myocardial infarction [MI]; mean age, 54 +/- 9 years) underwent exercise Tl-201 SPECT. The SPECT patterns were divided into normal (n = 45), fixed defects (n = 29), and inducible ischemia (n = 75).
