Value of the brain angioscintigraphy in posterior view
European Journal of Nuclear Medicine
|December 1, 1979
Summary
Intravenous brain angioscintigraphy (IBAS) effectively detects posterior cranial lesions in 45 of 61 patients. This diagnostic imaging technique reveals various perfusion patterns, aiding in the identification of brain abnormalities.
Area of Science:
- Nuclear Medicine
- Radiology
- Neurology
Background:
- Cerebellar, cerebral, or cranial lesions of posterior location present diagnostic challenges.
- Intravenous brain angioscintigraphy (IBAS) is a valuable tool for evaluating posterior fossa pathologies.
Purpose of the Study:
- To evaluate the efficacy of IBAS using 99mTc-DTPA(Sn) in patients with suspected posterior cranial lesions.
- To define normal IBAS characteristics in the posterior view.
Main Methods:
- IBAS was performed on 61 patients with suspected posterior cranial lesions and 100 controls.
- 99mTc-DTPA(Sn) was used as the radiotracer.
- Angioscintigraphic patterns were analyzed and correlated with morphological studies.
Main Results:
- Of 61 patients with suspected pathology, 45 showed angioscintigraphic alterations.
- Identified patterns included increased/diminished perfusion, flip-flop, mixed patterns, circulatory arrest, and jugular venous reflux.
- Normal IBAS findings were observed in patients with both abnormal and normal morphological studies.
Conclusions:
- IBAS is a sensitive method for detecting posterior cranial lesions.
- The study identified distinct angioscintigraphic patterns indicative of various pathologies.
- IBAS findings should be interpreted in conjunction with morphological studies for comprehensive diagnosis.
