Introduction  

Fenestrations of cerebral arteries are most common in the vertebrobasilar (VB) system, and magnetic resonance (MR) angiographic studies of these variations are sparse.     

Value of MR imaging in the differentiation of benign and malignant orbital tumors in adults

Purpose  

To prospectively evaluate magnetic resonance (MR) imaging including dynamic contrast-enhanced MR imaging in the differentiation of benign from malignant orbital masses and to evaluate which MR imaging features are most predictive of malignant tumors.     

Accuracy of computed tomography attenuation measurements for diagnosing anemia

Purpose  

The purpose of this study was to determine which computed tomography (CT) attenuation parameter was the most appropriate to predict the presence or severity of anemia.     

Knee arthroscopy routines and practice

Purpose  

Knee arthroscopy is one of most commonly performed day-case orthopaedic procedures, thus consuming huge medical resources. The aim of the present questionnaire survey was to study knee arthroscopy routines and practice.     

Musculoskeletal injuries in young ballet dancers

Purpose  

The aim of this study was to examine the incidence of musculoskeletal injuries, site and type of injury, and the most common injury diagnoses in young ballet dancers at the Royal Swedish Ballet School, a public school in Stockholm.     

Previous fracture surgery is a major risk factor of infection after total knee arthroplasty

Purpose  

Total knee arthroplasty (TKA) has been proven to be the most effective treatment for patients with severe joint disease. Although infection is not a frequent complication, it is certainly one of the most dreaded. The purpose of this study was to identify factors associated with infection after TKA.     

Accuracy of anatomical references used for rotational alignment of tibial component in total knee arthroplasty

Purpose  

This study aimed to research which was the most reliable of the four techniques based on local anatomic markers used to determine tibial component rotation in total knee arthroplasty, and whether the markers varied in knees with varus deformity.     

The effect of prophylactic knee bracing on performance: balance, proprioception, coordination, and muscular power

Purpose  

Prophylactic knee braces are largely used in the prevention of ligament injuries, but their effectiveness on performance are still controversial. The aim of this study was to determine which brace was the most effective on functional performance.     

Comparison of T2-weighted and contrast-enhanced T1-weighted MR imaging at 1.5?T for assessing the local extent of cervical carcinoma

Objective  

To compare two MR sequences at 1.5 T—T2-weighted and contrast-enhanced T1-weighted images—by using macroscopic sections to determine which image type enables the most accurate assessment of cervical carcinoma.     

Endocrine pancreatic tumours: which are the most useful MRI sequences?

Objectives  

To determine magnetic resonance imaging (MRI) signal and enhancement characteristics of endocrine pancreatic tumours (ETPs) and which MR sequences show them most consistently.     

Whole-body MRI using a sliding table and repositioning surface coil approach

Objective  

To introduce and assess a new way of performing whole-body magnetic resonance imaging (MRI) using a non-integrated surface coil approach as available on most clinical MRI systems worldwide.     

Determination of a standard deviation that could minimize radiation exposure in an automatic exposure control for pulmonary thin-section computed tomography

Purpose  

The aim of this study was to determine a standard deviation (SD) that most reduces the radiation dose without sacrificing the diagnostic accuracy of thinsection computed tomography (CT) for clinical use.     

ACL graft re-rupture after double-bundle reconstruction: factors that influence the intra-articular pattern of injury

Purpose  

To determine the most common rupture patterns of previously reconstructed DB-ACL cases, seen at the time of revision surgery, and to determine the influence of age, gender, time between the initial ACL reconstruction and re-injury, tunnel angle and etiology of failure.     

Diffuse vascular injury: convergent-type hemorrhage in the supratentorial white matter on susceptibility-weighted image in cases of severe traumatic brain damage

Introduction  

Susceptibility-weighted image (SWI) is one of the most sensitive methods for detect microbleeding and useful for evaluation of traumatic brain damage. The purpose of this study is to delineate the characteristics and importance of supratentorial deep white matter hemorrhages detected by SWI in cases of traumatic brain damage.     

Early functional outcome after subvastus or parapatellar approach in knee arthroplasty is comparable

Purpose  

In total knee arthroplasty, tissue-sparing techniques are considered more important, as functional gain could become more advantageous when early mobilization is commenced. The parapatellar approach is most often used, whereas the subvastus approach is a suitable alternative. Presently, it is unknown, according to true objective measurements, which of the two is most advantageous.     

Early FDG PET at 10 or 20 Gy under chemoradiotherapy is prognostic for locoregional control and overall survival in patients with head and neck cancer

Purpose  

Our study aimed to explore the optimal timing as well as the most appropriate prognostic parameter of ¹⁸F-fluorodeoxyglucose positron emission tomography (FDG PET) during chemoradiotherapy (CRT) for an early prediction of outcome for patients with head and neck squamous cell carcinoma (HNSCC).     

Improved liver lesion conspicuity by increasing the flip angle during hepatocyte phase MR imaging

Objective  

One of the advantages of using hepatobiliary contrast agents in liver MRI is the ability to acquire a delayed, “hepatocyte phase” dataset. This phase highlights many types of lesions as hypointense compared with the liver, because of the accumulation of contrast material in functioning hepatocytes and non-retention within most lesions.     

FDG PET evaluation of early axillary lymph node response to neoadjuvant chemotherapy in stage II and III breast cancer patients

Purpose  

Regional axillary lymph node status has remained the single most independent variable to predict prognosis both in terms of disease recurrence and survival. This study aimed to prospectively assess sequential [¹⁸F]fluorodeoxyglucose (FDG) positron emission tomography (PET) findings as early predictors of axillary lymph node response to neoadjuvant chemotherapy in stage II and III breast cancer patients.     

Mechanical axis-derived femoral component rotation in extramedullary total knee arthroplasty: a comparison between femoral transverse axis and transepicondylar axis

Purpose  

Correct rotational alignment of the femoral component is paramount to the success of total knee arthroplasty, but debate continues as to which method is the most reliable. The purpose of this study was to evaluate mechanical axis-derived rotational axis of the femoral component using an extramedullary femoral alignment guide system.
