Injury Detection in Traumatic Death: Postmortem Computed Tomography vs. Open Autopsy

ConclusionA combination of PMCT and autopsy can detect more injuries than either modality in isolation. PMCT detected a considerable number of injuries missed by autopsy and vice versa.

This study is focused on multiscale characterization and constitutive parameters identification of selectively laser sintered PA12 specimens. The process parameters and change in crystallinity due to 3D printing were identified via differential scanning calorimetry (DSC). Tension, compression, shear, flexural and fracture tests performed on samples fabricated, both in 0° and 90° directions reveal that the tensile toughness of samples printed in 0° orientation, outperform samples printed in 90° orientation by an average of 24%. Cryogenically fractured samples were analyzed via SEM and micro-computed tomograp...

A 25-year-old male with end-stage kidney disease from obstructive uropathy and neurogenic bladder presented to the emergency room with generalized tonic-clonic seizures. Two weeks before this presentation, the patient was started on hemodialysis via nontunneled precurved hemodialysis catheter, which was inserted into the right internal jugular vein. A cranial computed tomography obtained for the seizures revealed subcutaneous emphysema of the scalp and air bubbles within the dural venous sinuses (Figure  1a).

Although he archived negative sputum culture two months ago, sputum culture tests revealed the newly isolation of Mycobacterium abscessus repeatedly. Chest computed tomography showed newly-appeared extra-pulmonary mass lesion in contact with a cyst at the bottom of his right lung. From the results o...

Here we present a case in which a lung tumor, which resembled an atypical carcinoid tumor, was revealed as metastatic breast cancer by next generation sequencing. A 50-year-old female, who had received modified radical mastectomy for breast cancer, presented with a 2.1 cm sized lung mass. The ma...

Authors: Garbuglio R, Turchino D, Giribono AM, Viviani E, Ferrante L, Sodo M, Del Guercio L, Bracale UM Abstract Ancient Schwannoma is a type of peripheral neurogenic tumor formed by the Schwann cells presenting mainly as a benign and asymptomatic lesion. The neurilemmoma tumor appears in different sites and, in cases of cervical location, can mimic a carotid body tumor. Herein we describe a clinical case of a 51-year-old woman with latero-cervical swelling. A contrast-enhanced computed tomography scan revealed a classical wineglass image mimicking a carotid body tumor. During surgery the tumor appeared connected t...

Subject-specific features can contribute to the susceptibility of an individual to stress fracture. Here, we incorporated tibial morphology and material properties into a standard musculoskeletal finite-element (M/FE) model and investigated how load carriage influences joint kinetics and tibial mechanics in women. We obtained the morphology and material properties of the tibia from computed tomography images for women of three distinctly different heights, 1.51 m (short), 1.63 m (medium), and 1.75 m (tall), and developed individualized M/FE models for each. Then, we calculated joint and muscle forces, and subsequently, tib...

Objective: Aneurysm rupture risk can be assessed by its morphologic and hemodynamics features extracted based on angiographic images. Feature extraction entails aneurysm isolation, typically by manually positioning a cutting plane (MCP). To eliminate intra- and inter-rater variabilities, we propose automatic cutting plane (ACP) positioning based on the analysis of vascular surface mesh. Methods: Innovative Hough-like and multi-hypothesis-based detection of aneurysm center, parent vessel inlets, and centerlines were proposed. These were used for initialization and iterative ACP positioning by geometry-inspired cost function...

AbstractDistal humeral fractures represent approximately 2% of fractures in adults and are often treated operatively to restore stable humeral columns and allow early elbow motion. Diagnosis is made with orthogonal radiographs. The traction view radiograph and computed tomography with three-dimensional reconstruction can be helpful in preoperative planning. Treatment options include: (1) nonoperative management, which is reserved for lower-demand, medically unwell, elderly patients, (2) surgical osteosynthesis, which remains the treatment of choice for most fractures, and (3) prosthetic replacement with either hemiarthropl...
