Computed tomography of the mediastinum

CT is the most valuable diagnostic technique for the evaluation of suspected mediastinal masses when other conventional precedures become insufficient as a means of diagnosis. Using CT, a lesion suspected on the plain chest roentgenogram is easily confirmed, its location can be established more precisely and its relations to adjacent structures is accurately defined. With contrast enhancement, CT is reliable in distinguishing vascular from non- vascular structures and can determine whether the etiology is an anatomic variation or a pathalogic alteration of a mediastinal vascular structure. CT allows an accurate evaluation of the mediastinal lymph nodes especially the aorto-pulmonic nodes. CT os the most valuable radiologic technoque in the evaluation of the paraspinal widening

Computed tomography in comatosed patients

Computed axial tomography confirmed the clinical and operative diagnosis in 30 patients who were comatosed or had history of coma. The present study illustrated that CT can be of help in the diagnosis of many of intracranial lesions in comatosed patients and in planning further management of these patients. Causative intracranial lesions were found in 84.5%, while in the remaining patients [15.5%] where no positive intracranial lesions were found, the cause proved to be medical, such as metabolic and intoxication

Dynamic echohysteroscopy versus hysterosalpingography in assessment of tubal patency in cases of female infertility

Tubal obstruction is the commonest cause of infertility. The ability to diagnose tubal occlusion or patency using ultrasonic techniques eliminates unnecessary radiation and avoids the use of iodinated contrast media. Dynamic echohysteroscopy is a new technique in which sterile fluid is injected. A comparative study of hysterosalpingography versus dynamic echohysteroscopy in 50 patients with primary and secondary infertility was performed. Twenty-eight cases had primary infertility and 22 cases had secondary infertility. DEH in primary infertility showed bilateral tubal obstruction in three patients, unilateral tubal obstruction in six patients and 19 patients had patent tubes. In cases of secondary infertility bilateral tubal obstruction was found in one case and unilateral tubal obstruction in three patients and 18 cases had patent tubes. Correlation between HSG, DEH and laparoscopy were discussed
