Summary
Positron emission tomography (PET) can diagnose intracranial hematomas. However, PET is better for evaluating brain function than cerebral blood flow in these cases.
Area of Science:
- Neurology
- Radiology
- Nuclear Medicine
Background:
- Intracranial hematomas pose significant diagnostic challenges.
- Accurate assessment of cerebral blood flow is crucial for understanding brain function in neurological conditions.
Purpose of the Study:
- To investigate the utility of H2(15)O Positron Emission Tomography (PET) in diagnosing intracranial hematomas.
- To compare the effectiveness of PET with established methods for evaluating cerebral blood flow in patients with suspected hematomas.
Main Methods:
- Positron emission tomography (PET) using H2(15)O was performed on 5 patients with suspected intracranial hematomas.
- Cerebral blood flow was assessed as a reflection of H2(15)O distribution.
Main Results:
- Positron emission tomography (PET) demonstrated diagnostic capability for tunicary hematomas.
- The assessment of cerebral blood flow using PET was found to be suboptimal for this specific abnormality.
Conclusions:
- While Positron Emission Tomography (PET) can identify intracranial hematomas, its primary role in such cases lies in evaluating cerebral function.
- Computerized tomography remains the foundational imaging modality for diagnosing intracranial hematomas.
