A Comprehensive Analysis of Volumetric Ga-PSMA PET/CT Parameters, Clinical and Histopathologic Features: Evaluation of the Predictive Role.

Objectives: To evaluate the relationships between volumetric Ga-prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) parameters, Gleason score (GS), prostate-specific antigen (PSA) levels, histopathological data, and metastatic status in newly diagnosed prostate cancer (PCa) patients and to assess the predictive factors for progression despite treatment.

Methods: A total of 78 newly diagnosed patients with PCa who had Ga-PSMA PET/CT scans were included. Clinical parameters, histopathological data, and metastatic status were documented, and volumetric parameters of primary prostate lesions were measured.

EFFECTIVE HALF-LIFE, EXCRETION AND RADIATION EXPOSURE OF 177LU-PSMA.

The study aims to evaluate the radiation safety conditions by detecting the patient's urine excretion rate, calculating the effective half-life, and determining the retention of 177Lu-PSMA in the body. Urine samples of patients were collected for 24 hours (6, 12, 18, and 24 hours) following the infusion, excretion rate and retention of 177Lu-PSMA in the body of patients were calculated. The measurements of dose rate were performed.

Inguinoscrotal Bladder Hernia Mimicking Testicle Tumor.

Bladder hernias usually begin asymptomatically and are discovered incidentally at the time of discovery. Preoperative diagnosis of bladder hernias is important to reduce the risk of bladder injury during surgery. Although F-18 FDG PET/CT is applied for oncological purposes, benign conditions should also be taken into account when evaluating the implants.

Unexpected Metastatic Localizations of Prostate Cancer Determined by Ga PSMA PET/CT: Series of Four Cases.

Prostate-specific membrane antigen (PSMA) is a transmembrane protein with overexpression in most prostate cancer cells. Gallium-68-(Ga) PSMA positron emission tomography/computed tomography (PET/CT) imaging is a game-changer in the management of prostate cancer. Ga PSMA PET/CT scan is advanced and a promising radioligand has high sensitivity in determining lesions of prostate cancer with a high tumor to background ratio.

Contribution of Open Mouth Technique in F-FDG PET/CT Imaging in Patients with Malignant Lip Neoplasm.

Objectives: F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) plays an important role in evaluating head and neck cancers. However, localization and size evaluation in this region can be rough due to the multitude of the anatomic structures and physiologic uptakes. The aim of this study was to evaluate malignant lip lesions with the contribution of open mouth (OM) imaging technique at PET/CT.

Tuberculous Tenosynovitis of the Wrist: A Report of Two Cases with Special Reference to Magnetic Resonance Findings.

Background: Tuberculous tenosynovitis of the wrist is rare among cases of musculoskeletal tuberculosis. It is a slow, progressive disease with silent symptoms, leading to a late diagnosis. Also, it can be misdiagnosed as inflammatory arthritis, pyogenic infections, and inflammatory tenosynovitis.

Efficacy and cost-effectiveness of the cell saver system in instrumented posterior fusion with thoracic and lumbar vertebral fractures.

Background: The aim of our study was to determine the efficacy and cost-effectiveness of intraoperative autotransfusion that uses the cell saver system (CSS) in patients undergoing posterior instrumentation and fusion of thoracic and lumbar vertebral fractures.

Methods: We divided 121 patients who were to undergo posterior instrumentation and fusion due to thoracic and lumbar vertebral fractures into two groups: 59 patients (23 males and 36 females) were in the cell saver group, and 62 patients (22 males and 40 females) were in the control group. Hemoglobin, hematocrit, and red blood cell (RBC) values were recorded for all patients preoperatively, on the postoperative first, second, and third days, and on the hospital discharge day.

Ulnar variance according to gender and side during aging: An analysis of 600 wrists.

Background: Ulnar variance, or the difference in height between the joint surfaces of the distal radius and ulna, may play a role in several diseases of the wrist.

Hypothesis: This study was to conduct a detailed analysis of ulnar variance in a wider case series by dividing the patients' radiographs into groups according to age, gender, and side.

Materials And Methods: Twenty groups were created in order to investigate the change of ulnar variance according to age, gender, and side.

Ginkgo Biloba improves bone formation during fracture healing: an experimental study in rats.

Objectives: extract (EGb 761) is a plant extract obtained from the leaves of the tree. The aim of this study was to assess the histological and radiological effects of extract on fracture healing in an experimental fracture model using rat femurs.

Methods: Forty-eight female Sprague-Dawley rats (weight: 195-252 g; age: 20 weeks) were used in the study.

Evaluation of the Posterior Tibial Slope in Noncontact ACL Injuries Using Magnetic Resonance Imaging.

This study investigated whether an increased posterior tibial slope (PTS) was a risk factor for noncontact anterior cruciate ligament (ACL) injuries. We retrospectively evaluated the Magnetic Resonance (MR) images of 60 patients with noncontact complete ruptures of the ACL and 60 age-matched, healthy individuals with normal knee MR images. We measured the medial and lateral PTS on the sagittal T1W images separately in both the patients with complete ACL ruptures and the control group, as described by Hudek et al.

Pseudoaneurysm of the Common Digital Artery with Magnetic Resonance Imaging and Surgical Findings.

Pseudoaneurysms are rare and are most commonly caused by blunt trauma. Taking a clinical history and doing an examination are very helpful to clinicians in making a diagnosis. In addition, imaging methods are very useful in distinguishing a pseudoaneurysm from soft-tissue tumors.

Pseudoaneurysm of the Radial Artery on the Hand Secondary to Stabbing.

Pseudoaneurysm of the radial artery is extremely rare. It usually occurs secondary to trauma, interventional procedures, and infections. Symptoms occur due to mass effect by the pseudoaneurysm, digital ischemia, or nerve suppression.

Open Dislocation of Ankle without Fracture Treated with an External Fixator.

Ankle dislocations are orthopedic emergencies that require immediate treatment to avoid neurovascular impairment. They are usually accompanied by one or more comminuted fractures of the ankle mortis. In rare circumstances, such as high-energy trauma, the ankle dislocations may not be accompanied by concomitant malleolar fractures and, thus, are named "pure ankle dislocations".

The Occupancy of the Components in the Cervical Spine and Their Changes with Extension and Flexion.

Study Design Retrospective case series. Objectives The kinematics of the cervical spine has been investigated by many researchers. However, the occupancy of the disk bulges, spinal cord, ligamentum flavum, and the rest of the canal as well as the changes of these structures with motion have not yet been investigated.

Samarium-153 therapy for prostate cancer: the evaluation of urine activity, staff exposure and dose rate from patients.

The aim of this study was to determine the excretion of Samarium-153-ethylenediaminetetramethylphosphonic acid ((153)Sm-EDTMP) in urine and to calculate the dose rate of its retention in the body as a function of time and the dose received by the skin of laboratory staff's finger. Urine samples were collected from 11 patients after intravenous injection of (153)Sm-EDTMP. The measurements of dose rate were performed.

Dynamic changes of the ligamentum flavum in the cervical spine assessed with kinetic magnetic resonance imaging.

The purpose of this article is to quantify changes in thickness of the ligamentum flavum (LF) associated with motion of the cervical spine and to compare the thickness of the LF at each cervical level using kinetic magnetic resonance imaging (kMRI). Two hundred fifty-seven symptomatic patients (129 men; 128 women) underwent kMRI in neutral, flexion, and extension positions. Midsagittal images were digitally marked and electronically analyzed by spine surgeons.
