Comparative Study
[99mTc-MAG3 and 131I-OIH in patients with kidney insufficiency and with normal kidneys].
Renal clearance of 99mTc-mercaptoacetyltriglycine (MAG3) and 131J-orthoidohippurate (OIH) were compared by simultaneous measurement in 50 patients. Renal time-activity-curves of both radiopharmaceuticals were compared in 50 patients. ⋯ Renal time activity curves and relative renal function showed good correspondence in patients with normal (n = 13) and impaired (n = 7) renal function. It is concluded that MAG3 may be used as substitute for OIH in patients with normal and impaired renal function.

Ten patients with orbital fractures and optic nerve trauma are reported. Fractures of the optic canal could be demonstrated by computed tomography in six cases and fractures of the orbital apex in another three cases. Surgical decompression of the optic canal was performed in seven cases. Computed tomography enhanced decision for surgery in cases of intraorbital haematoma with exophthalmus and narrowing of the canal by bony fragments, especially in those patients presenting with incomplete or progressive visual disturbance.
