Pulsatility Index of Popliteal Artery in Patients with Isolated Calf Vein Thrombosis: A Novel Technique for Detecting Thrombosis.

Background: To investigate the usefulness of popliteal artery spectral doppler findings as a complimentary approach to isolated calf vein thrombosis (DVT).

Material/methods: We included consecutive patients presenting with symptomatic and sonographically proven acute isolated calf DVT. Patients with thrombosis of any other vein were excluded.

Morphometric Analysis of Styloid Process Using Multidetector Computed Tomography.

Styloid process (SP) is a cylindrical anatomical structure located at the anterior side of stylomastoid foramen. Normally, it is 20 to 25  mm in length and can vary with age and sex. An elongated SP is an unusual source of craniofacial and cervical pain.

The evaluation of morphometry of the mastoid process using multidetector computed tomography in a living population.

The aim of this study was to examine the relationships of the bony landmarks on the lateral surface of the mastoid process (MP). It was also the target of this study to reveal the importance of sexual dimorphism in terms of the mastoid triangle. Our study was performed on 140 (70 women, 70 men) multidetector computed tomography images obtained from patients who underwent radiologic examination at the Department of Radiology of Meram Medical Faculty, Necmettin Erbakan University.

The evaluation of morphometry of nasal bone and pyriform aperture using multidetector computed tomography.

Introduction: The aim of this study was to measure nasal bone (NB) and pyriform aperture (PA), morphometrically. Besides, the different types of NB and PA were classified and determined the sexual differences.

Materials And Methods: Our study was performed on 120 (60 women, 60 men) multidetector computed tomography images obtained from patients who underwent radiologic examination in the Department of Radiology of Meram Faculty of Medicine, Necmettin Erbakan University.

Where is the apex of the sacral hiatus for caudal epidural block in the pediatric population? A radio-anatomic study.

Purpose: Caudal epidural block (CEB), administered through the sacral hiatus, is a regional anesthetic technique commonly used in children. To facilitate and optimize pediatric CEB, morphometric data that may be important for the sacral hiatus have been obtained using multidetector computed tomography (MDCT).

Methods: This study is the first radio-anatomic study designed to address this topic in children.

Comparison of ventilation-perfusion scintigraphy with MR angiography in patients with Swyer-James syndrome.

Purpose: The aim of this study was to establish the value of magnetic resonance angiography (MRA) in diagnosing) Swyer-James syndrome (SJS) and to compare MRA and ventilation-perfusion (V/Q) scan results in patients with established SJS.

Methods: The V/Q scans and the MRA findings of 22 lungs of 11 patients with SJS (6 males, 5 females; age range: 17-69 years, mean: 38.4 years) were retrospectively studied.

Detection and quantification of the parenchymal abnormalities in emphysema using pulmo-CT.

We aimed to determine the degree and extent of parenchymal abnormalities on pulmo-CT in patients with emphysema. The study group consisted of 29 patients (18 male, 11 female; mean age 57.9+/-13).

Unusual congenital aortic anomaly with rare common celiamesenteric trunk variation: MR angiography and digital substraction angiography findings.

Magnetic resonance angiography and digital substraction angiography (DSA) findings in a case with a rare congenital thoracoabdominal aortic hypoplasia and common celiamesenteric trunk variation with occlusion of infrarenal abdominal aorta are described here. To our knowledge, this aortic anomaly has not been previously described in the English literature. DSA is the optimum imaging modality for determination of aortic hypoplasia, associated vascular malformations, collateral vessels, and direction of flow within vessels.

Testicular development, ultrasonographic and histological appearance of the testis in ram lambs immunized against recombinant LHRH fusion proteins.

Sixteen native ram lambs weaned at 10 wk of age were divided into two groups. Eight animals were immunized against LHRH with a mixture of two fusion proteins: ovalbumin-LHRH-7 and thioredoxin-LHRH-7. The immunized lambs received a primary immunization plus two booster immunizations at 4 and 12 wks.

[Multidetector computed tomography in the diagnosis of parathyroid adenomas: contribution of contrast enhancement pattern to diagnosis].

Purpose: Contrast enhancement patterns of parathyroid adenomas in the arterial and venous phases were evaluated with multidetector computed tomography and specificity of the method to characterize the lesions was investigated.

Materials And Methods: Arterial and venous enhancement patterns of parathyroid adenomas were evaluated retrospectively with multidetector computed tomography in 12 patients. All adenomas were removed surgically and the diagnosis was confirmed histopathologically.

Transesophageal echocardiographic detection of a pulmonary artery aneurysm complicated by thrombus.

The incidence of aneurysms of the pulmonary artery is known to be very low. Although diagnosis and evaluation of pulmonary artery aneurysms may be difficult without angiography, computed tomography and MRI's have emerged as useful noninvasive techniques. However, a transthoracic echocardiogram may reveal a pulmonary artery aneurysm.

MR fluoroscopy-guided transthoracic fine-needle aspiration biopsy: feasibility.

The purpose of this study was to evaluate the feasibility of using an open-configuration magnetic resonance (MR) imaging system with MR fluoroscopic guidance to perform percutaneous transthoracic fine-needle aspiration biopsy in patients with lung masses. Percutaneous transthoracic aspiration biopsies were performed with MR fluoroscopic guidance in 14 patients. The masses were 2-7 cm in diameter (mean, 4.

Clinical value of color Doppler ultrasonography measurements of full-term newborns with perinatal asphyxia and hypoxic ischemic encephalopathy in the first 12 hours of life and long-term prognosis.

The cerebral blood flow velocities (CBFV) of infants with perinatal asphyxia and hypoxic ischemic encephalopathy (HIE) in the first 12 hours of their lives have been the chief focus of our concern in this study. Cerebral ischemia which can develop in the earlier hours of HIE, and the detection and diagnosis of this condition with color Doppler ultrasonography (cD-USG) will be put into discussion. Twenty-three full-term newborn infants who had perinatal asphyxia and HIE together with a control group constituting twenty full-term newborn infants who produced no problems, were included in our study.
