Pulmonary Artery Obstruction Index and Right Ventricular Dysfunction Signs in Initial and Follow up Pulmonary Computed Tomography Angiography in Acute Pulmonary Embolism.

Intoduction: Acute Pulmonary Embolism (APE) increases the pressure of the pulmonary arterial system with resulting Right Ventricle Dysfunction (RVD).

Aim: The aim of this study was to evaluate the relationship between Pulmonary Artery Obstruction Index (PAOI) and signs of right heart dysfunction with computed tomography angiography in APE patients.

Materials And Methods: We evaluated 72 consecutive patients (mean age 64.

The impact of pre-procedural waiting period and anxiety level on pain perception in patients undergoing transrectal ultrasound-guided prostate biopsy.

Purpose: To investigate the effect of pre-procedural waiting period and anxiety level on pain perception during transrectal ultrasound-guided prostate biopsy.

Materials And Methods: Sixty patients who had undergone transrectal ultrasound-guided prostate biopsy were enrolled in this prospective study. The subjects were asked to fill out the State-Trait Anxiety Inventory Scale-1 to measure the level of state anxiety at three times: 1) at the time of the procedure request, 2) before the procedure, and 3) before getting the result.

The diagnostic efficiency of ultrasound guided imaging algorithm in evaluation of patients with hematuria.

Purpose: To assess the efficiency of the following imaging algorithm, including intravenous urography (IVU) or computed tomography urography (CTU) based on ultrasonographic (US) selection, in the radiological management of hematuria.

Materials And Methods: One hundred and forty-one patients with hematuria were prospectively evaluated. Group 1 included 106 cases with normal or nearly normal US result and then they were examined with IVU.

[Atypically located pulmonary adenoid cystic carcinoma: case report].

Pulmonary adenoid cystic carcinomas typically arise from central extra-pulmonary airways and lung involvement is rare. On the other hand, this entity should be kept in mind because it has a more favorable clinical course compared to the primary lung adenocarcinoma. In this paper; the clinical, radiological and pathological aspects of a 47 years old man with a complaint of chronic cough, who was found to have a mass lesion at upper lobe of right lung and a final diagnosis of primary pulmonary adenoid cystic carcinoma according to transbronchial needle biopsy and pneumonectomy, was presented.

Ultrasonographic prenatal diagnosis of isolated acephaly.

First trimester obstetric ultrasonography of a 32-year old female patient revealed a 13-week-old (according to the length of the femur and abdominal circumference) intrauterine live pregnancy with the absence of the fetal head. Medical abortus was performed with the diagnosis of acephaly and final diagnosis was confirmed by pathological and radiological examinations. We present and discuss the possible etiopathologic mechanisms of an acephaly case, which is described as acardia-acephaly complex in the literature, and usually appears in cases of twin reversed arterial perfusion sequence, but has not been previously reported as an isolated finding.

[The detectability of posterior portion of superior pericardial recess on routine chest CT].

The aim of this study was to search for the conspicuity, shape and size of posterior portion of superior pericardial recess (SPR) on routine spiral chest computed tomography (CT). Chest CTs of 180 consecutive patients were reviewed for the presence of the posterior portion of SPR, retrospectively. All images were reevaluated on a workstation by two radiologists in consensus with a constant window setting (window level 50 HU, window width 350 HU).

The effect of strabismus surgery on retrobulbar hemodynamics.

Purpose: To investigate the potential alterations of ocular hemodynamics after strabismus surgery using color Doppler ultrasonography.

Materials And Methods: Twenty eyes of 18 patients and the left eyes of 20 healthy age- and sex-matched volunteers were evaluated. Patients were divided into two groups according to the number of operated muscles.

Resistance and pulsatility index increase in capsular branches of testicular artery: indicator of impaired testicular microcirculation in varicocele?

Purpose: To evaluate the effect of clinical varicocele on testicular microcirculation using spectral Doppler analysis.
