“…regionaler washout) klinisch nutzbar gemacht werden, wobei die einzigartige, überlagerungsfreie Darstellung der myokardialen 201 T1-Speicherung durch die SPECT-Technik optimale Voraussetzungen bietet. Erste Ergebnisse der Quantifizierung von SPECT-Bildern im Rahmen der Routinediagnostik (5,10,15,18,25,29) deuten diesen Fortschritt bereits an und konnten mit der vorliegenden Untersuchung (Tab. 6) bestätigt werden.…”

Sensitivity and specificity of 201Thallium-SPECT in rest-exercise studies were evaluated in 129 patients in comparison to coronary morphology. In addition, the results of 70 patients, examined before and after dilatation of coronary stenoses by PTCA were obtained. In this group, quantification of SPECT images was tested. Sensitivity in detection of CAD was 93%, specificity 84%. False negatives were most frequently found in the posterior wall. After PTCA 73% of the segments improved. With quantification, an increase of vitality by 11.6% and a decrease of the redistribution factor by a value of 8 was documented. 201Thallium-SPECT of the myocardium was found to be very useful to both evaluate CAD and follow-up interventional procedures. A quantification of slice-images is useful to objectively reveal therapeutic success.

“…Therefore, three-dimensional quantitative analysis of 201 T1 myocardial SPECT data is expected to result in a similar improvement (2,4). However, only a few attempts have as yet been published (4,11,13). In this paper we present a new, semi-automated quantitative procedure which could easily be run on any microcomputer employing ECT-software.…”

A semiautomated method for three-dimensional quantification of stress/rest 201TI myocardial SPECT of the left ventricle (LV) is introduced. A total of 33 ringsegment-shaped regions of interest (ROIs) are distributed over 6 oblique (short axis cuts) double-slices (thickness 1.3 cm) from LV apex to base, commencing with 1 ROI for the apex up to 8 ROIs for the base (1-4-4-8-8-8). Within the last two double slices an additional adjacent ROI is automatically placed in the upper right quadrant to observe lung Tl-uptake. Correspondence of slices for exercise and rest is achieved by adjusting the long axis outlines rebuilt from summed profiles of 15 oblique slices of each examination. Calculated numeric arrays of the extracted parameters (vitality, washout and redistribution) are “displayed in a target-like two-dimensional polar fashion.
