Clinical value of immunoscintigraphy in the rectal carcinomas: immunoscintigraphy of rectal carcinomas.

Background/aim: The aim of this study was to evaluate the clinical reliability of the immunoscintigraphy with radiolabeled monoclonal antibodies for the detection of metastases and recurrences of rectal carcinomas.

Methodology: A total of 65 patients underwent immunoscintigraphy with radiolabeled monoclonal antibodies. Indication for that examination was suspicious rectal cancer or suspicious rectal cancer recurrence and/or metastases.

Scintigraphic detection of colon carcinomas with iodinated monoclonal antibodies.

Purpose: The aim of this study was to evaluate the clinical reliability of the immunoscintigraphy with iodinated monoclonal antibodies for the detection of metastases and recurrences of colon carcinomas.

Methods: A total of 45 patients with colon carcinoma was investigated with gamma camera, after intravenous application of iodinated monoclonal antibodies.

Results: The sensitivity of the method was 90%, specificity 86%, positive predictive value 93%, negative predictive value 80% and accuracy 87%.

[Evaluation of perfusion of transplanted microvascular flaps using radionuclide arteriography].

Microvascular flap by its autonomous circulation, following the transplantation in recipient region, provides the quantity of blood sufficient for nutritive needs of flap, but it also provides additional blood supply in the surrounding of recipient region. The evaluation of the relation of the tissues perfusion of transferred microvascular flaps and the tissues of surrounding recipient region was done in 33 patients, 15.24 months after the transplantation of microvascular flaps, by radionuclide angiography using Tc-99m in the form of MAA HAS or pertechnetate at the Clinic for Plastic Surgery and Burns of Military Medical Academy (MMA) and at the Institute for Nuclear Medicine of MMA.
