We tried to evaluate the usefulness of the transcranial color flow imaging (TCFI) as a noninvasive imaging method for Intracranial space occupied lesion (I-SOL) .
METHOD-TCFI (ATL, ULTRAMARK 9® 2.25 MHz phazed arrey, 90° sector scan) was applied from the.. bitemporal “acoustic window” to 22 meningiomas, 12 pituitary adenomas, 5 gliomas, I intraventricular tumor, 4 arteriovenous malformations (AVM), 7 intracerebral hematomas (ICH), 8 chronic subdural hematomas (CSH), 2 acute epidural hematomas (AEH), and 1 pediatric arachnoid cyst. RESULT-We were able to detect 12 meningiomas, 7 adenomas, 1 cystic glioma, 1 ventricular tumor, 2 AVMs, 6 ICHs, 6 CSHs, 2 AEHs, and 1 arachnoid cyst, as clearly defined lesions on B-mode images.
It was difficult to visualize the region of the posterior fossa. Frontal and high convexity regions were also difficult to investigate. CONCLUSION-TCFI has great advantages : movability, noninvasiveness and blood flow detection factors. It provides an useful diagnostic method for the I-SOL.
