Changes of brain perfusion after endovascular embolization of intracranial arteriovenous malformations visualized by 99mTc-ECD SPECT.

Objective: Published data describing scintigraphic evaluation of perfusion changes in patients with cerebral arteriovenous malformations (AVMs) after embolization are very scarce. The aim of our study was to evaluate these changes by using Tc-ethyl cysteinate dimer single photon emission computed tomography.

Materials And Methods: The examinations were performed in 20 patients before and after the treatment.

Evaluation of the left ventricular hemodynamic function and myocardial perfusion by gated single photon emission tomography, in patients with type 1 diabetes mellitus; prodromal signs of cardiovascular disease after four years.

The aim of this study was to assess the changes in hemodynamic function and myocardial perfusion of the left ventricle occurring in patients with type 1 diabetes mellitus (DM1) 47-49 months after the first assessment. We have studied 20 asymptomatic patients, five females and 15 males, aged 22-46 y. The patients were under intensive insulin treatment and had normal electrocardiogram (ECG) at rest.

[Lymphoscintigraphy in oncology--the role in the preoperative diagnosis].

Lymphoscintigraphy is the nuclear medicine procedure, which visualize the distribution of radiolabelled particles in the lymph vessels and lymph nodes. The sentinel node concept presumes that the first lymph node to receive drainage from a tumour will show the metastasis if there has been lymphatic tumour spread. Detection of metastatic involvement of lymph nodes is essential for management and prognostic evaluation in cancer patients.

Bone turnover markers and bone scintigraphy in the evaluation of the skeletal metastases.

Background: The aim of this study was evaluation of the clinical usefulness of bone scintigraphy and of serum bone turnover marker levels in the assessment of skeletal metastases.

Material And Methods: We investigated 60 patients with suspected skeletal metastases. Serum level of bone-formation marker: amino-terminal propeptide of type I procollagen (PINP) and a bone-degradation marker: carboxy-terminal telopeptide of type I collagen (ICTP) were assessed with radioimmunoassays.

[SPECT imaging of cerebral arteriovenous angiomas. A preliminary report].

Background And Purpose: The purpose of this study was to demonstrate scintigraphic evaluation of cerebral perfusion in patients with intracranial hemangiomas.

Material And Method: The examination was carried out in 12 patients aged from 12 to 67 years. In all the patients cerebral angiomas were previously diagnosed and all of them were qualified for intravascular embolization.

Diagnostic value of cerebral perfusion scintigraphy in evaluation of intracranial arteriovenous malformations--preliminary report.

Background: Arteriovenous malformations (AVM) markedly alter the distribution of the regional cerebral blood flow, as they consist of abnormal arteries and veins with no resistance vessels between them. The aim of this study was to the evaluate diagnostic utility of cerebral perfusion scintigraphy (dynamic phase and SPECT) in patients with AVM.

Material And Methods: Nineteen patients were examined.

[Thyrotropin receptor antibodies (TRAb) as a test of surgical treatment effectiveness in Graves-Basedow's diseases].

The aim of the study was to assess the relations between the concentration of antibodies against TSH receptors (TRAb) and the outcome of the surgical treatment in Graves-Basedow's disease. The studies were performed in 30 patients (age range--18-50, mean -37) operated on for Graves-Basedow's disease and in 20 healthy controls. In control group, the TRAb concentration was mean -2.
