Determining carpal collapse

This study included 50 subjects divided into two groups. Group I [control] comprised 30 healthy persons, 16 males and 14 females with ages ranged between 25 - 50 years with normal wrists were evaluated to obtain normal carpal anatomy. Group II [patients] comprised 20 patients, 10 males and 10 females, with ages ranged between 15 - 40 years. Seven of them suffering from rheumatoid arthritis, six suffering from Kienbock disease, and seven had non United fracture of scaphoid. A posteroanterior view of both wrists were done to determine the carpal height ratio and carpal height index to evaluate the progression of the collapse of the wrists in them. In this study the carpal height index was superior to carpal height ratio in evaluation of unilateral wrist disease and can be used accurately, reproducibly and quantitavely to evaluate stage III Kienblock disease, nonunited fracture of scaphoid and rheumatoid arthritis

Ultrasound and plain abdominal radiography [KUB] versus excretory urography in evaluating acute flank pain

This study included 72 patients, 57 males and 15 females with ages ranged between 12 - 59 years, presenting with renal colic. Plain X-ray of urinary tract, ultrasound of urinary tract and intravenous pyelography were done for all of them, in addition to their clinical evaluation and urine analysis. It appeared that the combination of ultrasound and plain X-ray of the urinary tract represented an effective and a safe method of evaluating patients with renal colic. While intravenous pyelography should be reserved for patients who will undergo interventional procedures and for patients with presistant colic in whom ultrasound and plain X-ray urinary tract were undiagnostic

Focal hepatic lesions: ultrasonic halo sign and doppler flow characteristics

We studied 53 focal hepatic lesions with real time ultrasound and duplex doppler US. Halo sign was seen in 14 1[ry] hepatic carcinomas, 30 metastases and 9 benign lesions. Peritumoral doppler flow was detected in 50% of both the 1[rh] hepatic carcinoma and metastases, but only in 11.1% of benign lesions. Intratumoral flow was in 50% of 1[ry] carcinoma and 88.9% of benign hepatic lesion. While mixed peri and intratumoral flow was only in 50% of metastases. The peak systolic flow velocity in 1[ry] hepatocellular carcinomas and metastases exceeded that of benign lesions. No difference in resistive index was detected between any of the hepatic focal lesions

Role of CT in paranasal sinusitis

This study included 70 patients [50 males and 20 females], their ages ranged between 10 and 60 years, presenting with clinical signs of sinusitis. Coronal computerized tomography was done for all of them in addition to their clinical evaluation and plain radiography and sinoscopy. Direct coronal CT can readily demonstrate disease in the infundibulum, frontal recess and posterior ethmoid in the same orientation confronting the endoscopist and helps in planning of ethmoidal surgery. In patients with persistent complaints after sinus surgery, CT is mandatory because inflammatory changes in the middle meatus are poorly seen on plain radiographs. It is important that the diagnosis of sinusitis is not based on CT finding alone as isolated areas of mucosal thickening are common in the normal population

CT versus MR in epilepsy

One hundred twenty seizure patients with positive EEG were studied using CT and MR to determine the efficacy of each in detection of epileptic focus. MR was considered to be the imaging procedure of choice for detection of an epileptogenic focus in seizure patients. When indicated, CT may be done as a second procedure to distinguish neoplasms from thrombosed vascular malformations, or to detect small foci of calcification and other lesions
