BACKGROUND Object detection in 3-D medical images is often necessary for constraining a segmentation or registration task. It may be a task in its own right as well, when instances of a structure, e.g. the lymph nodes, are searched. Problems from occlusion, illumination and projection do not arise, making the problem simpler than object detection in photographies. However, objects of interest a...

INTRODUCTION Sound knowledge of the external and internal morphology of the different teeth groups is essential to ensure a successful outcome of root canal treatment. The aims of this study were to review the available literature with respect to the root and root canal morphology of maxillary first premolars and discuss the clinical considerations of this morphology on the various dental proce...

Bilateral paramedian thalamic stroke is a special ischemic pattern that results from occlusion of the artery of Percheron (AOP), a rare anatomic variant of the paramedian arteries. We report a case of bilateral thalamic infarctions, with a dramatic improvement after thrombolysis. DSA demonstrated recanalization of AOP with possible unreported variation.

Anatomic pathology, along with the role of anatomic pathologists, has significantly evolved over past several years [...]

Pulmonary adenocarcinoma is one of the major types of lung cancers in which metastasis is not uncommon. Hereby, we report a case of pulmonary adenocarcinoma with multiple muscular, cutaneous, pancreatic and peritoneal metastases. Actually, all these features occurring in one patient makes it an extraordinary case. A rare anatomic variation, double inferior vena cava (IVCs), was another rare man...

Computer-based surgical simulation promises to provide a broader scope of clinical training through the introduction of anatomic variation, simulation of untoward events, and collection of performance data. We present a hapticallyenabled surgical simulator for the most common techniques in diagnostic and operative hysteroscopycervical dilation, endometrial resection and ablation, and lesion exc...

The right hepatic artery is an important arterial supply to lobe of the liver. And knowledge normal anatomy and anatomical variations essential perfume, will minimize morbidity, also help decrease number complications hepatobiliary surgery. This study was conducted on eleven human cadavers, which were obtained from routine autopsies at dissection room Anatomy Department. During cadaveric livers...

BACKGROUND AND PURPOSE Understanding the anatomy of the anterior septal vein (ASV) is critical for minimally invasive procedures to the third ventricle and for assessing lesion size and venous drainage in the anterior cranial fossa. Accordingly, this study evaluated topographic anatomy and anatomic variation of the ASV using susceptibility-weighted imaging (SWI). METHODS Sixty volunteers were...
