Radionuclide imaging in the diagnosis of liver trauma.

Thirty-three consecutive patients were examined on the clinical suspicion of traumatic rupture of the liver. In 13 patients liver rupture or liver haematoma was found on scintigraphy. In 5 of these patients the scintigraphic observation was verified by surgery. In two of these patients rupture of the spleen was suspected by the clinician, but rupture of the liver was found instead.

Subphrenic abscess.

A series of 39 patients with subphrenic abscess is presented. Nine of the patients had primary abscesses. In 27 patients, the abscess occurred postoperatively, after various abdominal operations, most frequently after gall bladder and gastric surgery. The value of combined lung-liver scintigraphy is stressed, as is promptly established and adequate drainage, using a selective surgical approach. There were 4 deaths in the series.

Emergency radionuclide demonstration of Meckel's diverticulum in a patient with perforated ulcer and massive rectal bleedings.

A 10-month-old infant was treated for life-threatening rectal bleeding caused by a perforated ulcer in Meckel's diverticulum. Radionuclide imaging with 99mTc-pertechnetate was used to demonstrate the diverticulum preoperatively. Early intervention is desirable to avoid uncontrollable bleeding or complications such as perforation in cases of Meckel's diverticula. Routine 99mTc-pertechnetate imaging as recommended today requires prolonged fasting, and its use in emergency situations may be questioned. This case, however, illustrates the usefulness of radionuclide imaging on an emergency basis as well as in the daily routine.

Radionuclide imaging of splenic laceration and trauma.

Tc-99m colloids are the pharmaceuticals preferred in the radionuclide diagnosis of splenic rupture. Spleen scintigraphy is also the preferred diagnostic method. It is rapid, safe, and reliable and should be recommended in all clinical situation where diagnosis is in doubt. A most important point is its value in following the healing of a splenic rupture managed nonoperatively or by suturing or resection, treatment modalities which are increasingly used at the present time.

The value of radioisotope renography in the followup of patients operated upon for hydronephrosis.

Isotope renography and excretory urography were perfored routinely before and 3 months after an operation on 21 patients with hydronephrosis. A year postoperatively all patients again underwent renography. Renography is a valuable and reliable method to estimate the results of an operation. By 3 months postoperatively the renograms revealed improved renal function and drainage in 75 per cent of the cases.

Computed tomography and scintigraphy in the diagnosis of splenic injury.

In a prospective study of 48 patients suspected to have splenic injury, the diagnostic value of computed tomography (CT) and scintigraphy was investigated. Both methods showed high sensitivity, demonstrating 27 of 28 ruptures. The specificity was 100% for CT and 80% for scintigraphy, since the latter method gave four false-positive diagnoses with regard to rupture and bleeding. Scintigraphy, however, has advantages over CT in children and noncooperative adults and is highly suitable in local trauma to the left lower thorax. CT is preferable in cases with possible trauma to multiple organs, such as commonly occurs in traffic accidents, and also provides a rough estimate of the extent of bleeding.
