We think elongations of T 1 and T 2 in surrounding tissues mean ischemic or necrotic changes in these areas induced by steal phenomena due to arteriovenous shunting. ![]() These tendencies were confirmed by measurement of T 1 and T 2 in ROI compared with contralateral side. And it is noteworthy that surrounding areas of AVM on calculated T 1 and T 2 images were observed as tissues showing elongated relaxation time in all cases. On images of NMR, nidus and many dilated vessels were distinctly revealed as low or no signal intensity area in all cases without contrast media. With this machine, we observed images of AVM and its surrounding tissue, made calculated images of T 1 and T 2 relaxation time and measured T 1 and T 2 values of ROI. We are using 0.15 Tesla NMR-CT (resistive type) produced by Bruker Company in West Germany and its pulse sequence is Carr-Purcell-Meiboom-Gill (CPMG) method which is best reformed type of spin echo. Intracerebral or subarachnoid hemorrhages due to rupture of AVM can be detected by X-ray CT scan, however, it is difficult to obtain three dimensional image of changes in the surrounding area of AVM that has never experienced hemorrhagic attacks. Patients with cerebral arteriovenous malformation (AVM) show various clinical symptoms, but they can be divided into two groups one resulting from rupture of AVM and another derived from chronic ischemia in surrounding tissues of AVM. Increased ONS diameter on MR images is a strong indicator of increased ICP we propose 6 mm as the normal limit of diameter just behind the eyeball because this value corresponds to the upper normal limit of ICP of around 20 cmH 2O with above mentioned approximate curve. The ONS diameter before surgery (6.1☐.7 mm) was significantly reduced after surgery (4.8☐.9 mm, p=0.003). y: ONS diameter (mm), x: subdural pressure (cmH 2O), correlation coefficient: 0.505). Significant correlation was found between the ONS diameter and subdural pressure (y=0.0618x+4.8219. ![]() Subdural pressure was measured using a manometer before opening the dura mater during surgery. Orbital thin slice fat-saturated MR images were obtained within 24 hours before surgery and ONS diameters were measured just behind the optic globe. We analyzed the relationship between subdural pressure measured during surgery in patients with chronic subdural fluid collections and ONS diameter measured on MR images.
