EVOKED POTENTIALS AND Tc-99m-HMPAO SPECT IN CEREBRAL INFARCTION PATIENTS

The present study aims at assessing the correlation between the regional cerebral blood flow and the functional state of the afferent and efferent conductive systems in 12 patients with hemispheric cerebral infarctions. All patients underwent a battery of tests: Tc-99m-HMPAO SPECT, somatosensory evoked potentials (SSEP), motor evoked potentials (МЕР), and sympathetic skin responses (SSR). The above mentioned investigations were performed twice: 48 hours and two weeks after the cerebral infarction onset. The positive correlation between the regional cerebral blood flow (rCBF) and the electrophysiologic parameters reflected the presence of a moderate dependence between the cerebral perfusion changes and neural conductivity

Restaging role of 18F-FDG-PET/CT in a patient with a Malignant Peripheral Nerve Sheath Tumor (MPNST) caused by neurofibromatosis – case report

Malignant Peripheral Nerve Sheath Tumors (MPNST) are a malignant disease that originates in the cells that cover and protect the peripheral nerves. They are a rare disease, accounting for 6% of soft tissue sarcomas. We present a patient with a malignant peripheral nerve sheath tumor on the left brachium with neurofibromatosis. The patient underwent whole body PET/CT for restaging after total extirpation of a tumor formation originated from n. musculocutaneous in 09.2017, an excision of a recurrent tumor formation in the proximal half of the brachium invading into m. biceps brachii in 12.2017, a performed MRI in 02.2018 - with data for multiple MPSNT in the area between the two previous operations - and subsequent definitive radiotherapy (boost) in the area of the tumor formation and 6 cycles of chemotherapy with Epirubicin. After restaging PET/CT scan of the whole body was performed, progression of the disease was defined - increased in size and activity subpleural lesion in the lower lobe of the right lung

EVALUATION OF GASTRIC EMPTYING IN REFLUX DISEASE AND DUODENAL ULCER PATIENTS

Thirty healthy volunteers, 77 hiatus hernia and reflux disease patients as well as 26  duodenal ulcer ones were studied by means of echographic planimetry and volumetry of antrum and corpus ventriculi and gamma camera as well in order to evaluate the gastric emptying before and after surgery. The mean semi-emptying antral time after esophagocruroplasty plus frontal semi-fundoplication was determined as 9,5 min whereas after Nissenfundoplication it reached the rate of 19,2 min (range 8-32 min; p < 0,001). The latter was related to a higher incidence rate of postoperative stomach bloating complaints with the N is sen patients. Ultrasound measurements of gastric emptying were of comparable sensitivity to scintigraphy in quantifying the fluid bolus evacuation

Monitoring the effect of therapy on a patient with a neuroendocrine tumor of the pancreas with PET/CT, 68Ga-DOTATATE - case report

Neuroendocrine tumors (NET) are a rare diagnosis, often without symptoms or mimicking other different symptoms. Тhey are a heterogeneous group of tumors derived from neuroendocrine cells, most commonly of the gastrointestinal tract, but may originate also from other organs including the pancreas, lungs, ovaries, thyroid, pituitary, and adrenal glands (3). Due to the difficult diagnosis, NET‘s are detected at a late stage in their development, often already locally advanced or metastasized. PET/CT with 68Gallium DOTATATE proved to be an effective imaging method not only for the primary diagnosis of NET and subsequent therapeutic behavior, but also for evaluating the effect of the treatment. (1) We present a case of a positive PET/CT scan, performed with Ga-68 DOTATATE in the topical location of the tail of the pancreas after therapy with Sandostain lar
