Comparison of QCT and DEXA findings for lumbar vertebra in young adults and the elderly.

Background: The use of dual-energy X-ray absorptiometry (DEXA) and quantitative computed tomography (QCT) methods are important for the diagnosis and follow-up of osteoporosis, and are used especially in cases to determine the degree of osteoporosis and the risk of fracture, monitoring the effectiveness of the treatment applied.

Purpose: To compare the parameters measured using the DEXA method from the lumbar (L1-L4) vertebrae and the Hounsfield unit (HU) values measured with QCT at the same levels among young adults and the elderly.

Material And Methods: The study included 155 patients (age range = 26-93 years).

The width and height of sinuses were measured on a coronal plane, and the anteroposterior length was measured on an axial plane.

Successful Retrieval of the Detached Porous Metallic Tip of a Mechanical Aspiration Catheter during Thrombectomy in a Case with May-Thurner Syndrome: A Case Report.

Modern, minimally invasive techniques used to treat deep venous thrombosis, such as percutaneous mechanical thrombectomy (PMT) and catheter-directed thrombolysis, have gained worldwide acceptance. PMT has the advantage of speed and is also associated with improved outcomes, shortened hospital stays, and low complication rates. The main complications associated with PMT have been primarily due to iatrogenic vascular damage resulting in perforation, embolic occlusion, and arteriovenous fistula formation; to date, there has been no publication in the literature describing complications resulting from device failure.

Comparison of placental elasticity in normal and pre-eclamptic pregnant women by acoustic radiation force impulse elastosonography.

Aim: The aim of this research was to study and compare placental elasticity with acoustic radiation force impulse (ARFI) elastography in pre-eclamptic and normal pregnancies.

Imaging Findings for Bilateral Giant Vestibulocochlear Schwannoma.

Neurofibromatosis type 2 mostly develops with multiple neoplasms of the central and peripheral nervous system and is associated with ocular abnormalities. The presented case is a 19-year-old female patient with bilateral vestibulocochlear schwannomas in both pontocerebellar corners, intradural intra-extramedullary masses, and multiple neurofibromas in the spinal canal. The clinical picture for NF-2, also called central neurofibromatosis, is completely different from von Recklinghausen disease.

Hemolytic Uremic Syndrome Causing Multicystic Leukoencephalomalacia.

Backgrund: Hemolytic uremic syndrome is a disease characterized by hemolytic anemia, thrombocytopenia and acute renal failure with multiple organ involvement. Central nervous system involvement is detected in 20-50% of the patients and this leads to increased morbidity and mortality.

Case Report: We report the neuroimaging findings in a four-month-old male with hemolytic uremic syndrome.

Ultrasound Elastography for Distinction Between Parathyroid Adenomas and Thyroid Nodules.

Objectives: The aim of this study was to detect the level of stiffness of parathyroid adenomas and to distinguish them from benign and malignant thyroid nodules using ultrasound elastography with acoustic radiation force impulse imaging.

Methods: Twenty-one patients with parathyroid adenomas and 71 patients with thyroid nodules were evaluated by acoustic radiation force impulse imaging in this study. Acoustic radiation force impulse elastograms were obtained after evaluation of the thyroid nodules, which were predicted to undergo fine-needle aspiration biopsy, and patients with a diagnosis of hyperparathyroidism, which was identified by sonography at the same time.

The utility of ultrasound elastography in differentiation of endometriomas and hemorrhagic ovarian cysts.

Purpose: To investigate the feasibility of acoustic radiation force impulse imaging in differentiation of endometriomas and hemorrhagic ovarian cysts.

Materials And Methods: We evaluated 84 ovarian cysts with high internal echogenicity diagnosed in 70 consecutive women. We excluded simple cysts and hemorrhagic cysts containing septations or mural nodules with detectable flow on Doppler ultrasonography.

Decreased Vertebral Artery Hemodynamics in Patients with Loss of Cervical Lordosis.

BACKGROUND Because loss of cervical lordosis leads to disrupted biomechanics, the natural lordotic curvature is considered to be an ideal posture for the cervical spine. The vertebral arteries proceed in the transverse foramen of each cervical vertebra. Considering that the vertebral arteries travel in close anatomical relationship to the cervical spine, we speculated that the loss of cervical lordosis may affect vertebral artery hemodynamics.

A Rare Presentation of Transfusional Hemochromatosis: Hypogonadotropic Hypogonadism.

Hemochromatosis is a disease caused by extraordinary iron deposition in parenchymal cells leading to cellular damage and organ dysfunction. β-thalassemia major is one of the causes of secondary hemochromatosis due to regular transfusional treatment for maintaining adequate levels of hemoglobin. Hypogonadism is one of the potential complications of hemochromatosis, usually seen in patients with a severe iron overload, and it shows an association with diabetes and cirrhosis in adult patients.

Hepatic Artery Pseudoaneurysm: Delayed Presentation after a Blunt Trauma.

Background: Ruptured hepatic artery pseudoaneurysm is a rare condition that is life-threatening if not diagnosed and treated rapidly. We present a case of a spontaneously ruptured hepatic artery pseudoaneurysm that occurred after a blunt trauma, and provide a review of the current literature on this topic. This case study demonstrates a spontaneously ruptured hepatic artery pseudoaneurysm which emerged following a blunt trauma and it also presents current literature studies on the topic.

Spontaneous Rupture of the Middle Fossa Arachnoid Cyst into the Subdural Space: Case Report.

Background: Arachnoid cysts are congenital, benign and intra-arachnoidal lesions. A great majority of arachnoid cysts are congenital. However, to a lesser extent, they are known to develop after head trauma and brain inflammatory diseases.

Brain magnetic resonance imaging and magnetic resonance spectroscopy findings of children with kernicterus.

Background: The term kernicterus, or bilirubin encephalopathy, is used to describe pathological bilirubin staining of the basal ganglia, brain stem, and cerebellum, and is associated with hyperbilirubinemia. Kernicterus generally occurs in untreated hyperbilirubinemia or cases where treatment is delayed. Magnetic resonance imaging (MRI)-based studies have shown characteristic findings in kernicterus.

Acoustic Radiation Force Impulse (ARFI) elastography quantification of muscle stiffness over a course of gradual isometric contractions: a preliminary study.

Aims: To evaluate the feasibility of quantitative analysis of muscle stiffness by Acoustic Radiation Forced Impulse (ARFI) elastography over a course of graduate isometric voluntary contractions.

Material And Methods: The stiffness of the bilateral biceps muscle of 13 healthy volunteers was measured in real time by ARFI elastography, while the forearm was in neutral-extended position, 90 degree self-flexed positions and 90 degree self-flexed position, with altered weights ranging from 1 to 8 kg placed on flattened palmar surfaces consecutively. The determined increases in biceps muscle stiffness were measured for both arms and correlated with the loadings weights adopted at progressive trial stages.

Anterior hepatic grooves accompanied by Chilaiditi sign: a retrospective radiological analysis of a neglected anatomical fact.

Purpose: To evaluate anterior hepatic grooves (AHGs) associated with hepato-diaphragmatic mesocolic indentations (Chilaiditi sign) and to delineate the incidence and potential clinical significance of this association.

Os calcaneus secundarius is one of several accessory ossicles of the foot that have been identified as normal variants of skeletal development. It may cause ankle pain and may mimic an avulsion fracture of the anterior calcaneal process. A twenty-year-old male was admitted to our institution with right ankle pain following an inversion injury.
