“…Notwithstand¬ ing the difference in absorption coef¬ ficient and homogeneity between the renal tissue and the brain, cysts smaller than 1 cm have recently been identified in the kidney with a CT body unit. 18 On the basis of only one CT scan, it may be extremely difficult to make a conclusive diagnosis of recent cerebral infarction rather than glioblastoma, metastasis, or vascular malformation. Follow-up studies may then be advis¬ able.…”

Twenty patients with cerebral infarction were observed with serial computerized tomographic (CT) scans. Seventy percent of those infarctions showed a mass effect that had disappeared in all patients by the eighth week after the ictus. In 63%, there was enhancement after contrast infusion, with a definite temporal relationship to the day of onset of the neurological deficit. Twenty percent of the patients initially had normal CT scans that became abnormal weeks after the stroke. Radionuclide scans were positive in the patients who showed contrast enhancement, and the area of abnormal uptake correlated well with the area of enhancement. The timing of the performance of the CT scan in relation to the onset of neurological deficit is an important factor to consider when evaluating the stroke syndrome with CT.

“…Since the first collected reports of body CT in July 1976 [14], at least 88 abdominal abscesses documented by CT have been reported [4,[15][16][17][18][19][20][21][22][23][24]. Second, angiocatheter exchange techniques permit safe introduction of drainage catheters over guide wires although the initial puncture is made with only a 20-gauge needle [9].…”

Computed tomography (CT) is effective in demonstrating abdominal abscesses and their relation to surrounding structures. The CT signs of abscess are not unlike those demonstrable radiographically and include an abnormal mass, obliteration and displacement of surrounding organs, inappropriate gas, and peripheral enhancement after intravenous contrast. Axial imaging permits selection of safe approaches through which percutaneous needle aspiration can be performed for diagnosis and therapy. When techniques similar to those employed in angiography are used, a catheter can be inserted, the abscess evacuated, and the catheter left in place as a drain. Combined with intravenous antibiotics, this method of abscess drainage has been successful in curing abscesses without surgery. Representative examples are shown.

“…They can usually be differentiated from metastatic lesions because they are more sharply circumscribed and are less dense than metastatic tumor; however, care must be taken in their analysis since liver metastases may be present in patients with obstructive jaundice. Stanley et al [9] have demonstrated that computed tomography is highly accurate in differentiating obstructive from non-obstructive jaundice.…”

“…Recently, advances in design have allowed this technique to be used in the evaluation of other regions of the body. Several whole body scanners have been in use for one or more years and preliminary reports have demonstrated their usefulness particularly in examining the abdomen [4][5][6][7][8][9]. An EMI CT 5000 body scanner has been in use at the Rush-Presbyterian St. Luke's Medical Center since April 1976 and examples of its application will be demonstrated.…”

Computed tomography of the abdomen: Initial experience

Computed tomography has provided a new dimension in the roentgenologic evaluation of the abdomen. Normal structures not visible on conventional examinations are clearly identified. Abnormalities are recognized by their alterations in anatomic form or by their effect on tissue absorption values. Our early experience suggests that in the abdomen computed tomography will be most valuable in detecting lesions in those sites least accessible to conventional roentgenographic methods such as the liver, spleen, pancreas and retroperitoneum.
