The value of fine needle aspiration cytology in the clinical management of rare salivary gland tumors
Conclusion FNAC is a reliable diagnostic tool for common salivary gland neoplasms; however, rare tumors often represent diagnostic challenges. Clinical relevance In such rare tumors, the role of aspiration cytology may be limited to establishing the dignity of the lesion (benign/malignant). This knowledge enables the surgeon to choose the most appropriate therapeutic procedure. A definitive diagnosis of rare tumors (either epithelial or nonepithelial) is obtained by histological examination; cytology is limited in this regard due to overlapping features.

Evaluation of contrasting techniques for X ‐ray imaging of velvet worms (Onychophora)
Summary Non‐invasive imaging techniques like X‐ray computed tomography have become very popular in zoology, as they allow for simultaneous imaging of the internal and external morphology of organisms. Nevertheless, the effect of different staining approaches required for this method on samples lacking mineralized tissues, such as soft‐bodied invertebrates, remains understudied. Herein, we used synchrotron radiation‐based X‐ray micro‐computed tomography to compare the effects of commonly used contrasting approaches on onychophorans – soft‐bodied invertebrates important for studying animal evolution.

Tracheal agenesis: optimization of computed tomography diagnosis by airway ventilation
We describe a procedure of airway management applied in two newborns with suspected tracheal agenesis. Correct airway management was performed immediately prior to CT examination by airway ventilation, with bag-valve mask alone in one case, and attached to an endotracheal tube placed into the esophagus in the other case. The images allowed for classification of tracheal agenesis. Computed tomography with appropriate airway ventilation is fundamental for the diagnosis of tracheal agenesis.

Double superior vena cava: presentation of two cases and review of the literature.
CONCLUSIONS: Double SVC can be fortuitously discovered during catheter insertion, thoracic or cardiac imaging and surgery. In most cases it drains into the left atrium, through the coronary sinus. This entity is significant to the physician because of its importance in differential diagnosis as a cause of a widened mediastinum, as well as any difficulty that can occur in the placement of a central venous catheter or a pace maker.

Measuring Left Ventricular Size in Non–Electrocardiographic-gated Chest Computed Tomography: What Radiologists Should Know
Non–electrocardiographic (ECG)-gated computed tomography (CT) of the chest is one of the most commonly performed imaging studies. Although the heart is included in every CT study, cardiac findings are commonly underreported in radiology reports. Left ventricular size is one of the most important prognostic markers in multiple cardiac diseases and can be measured on almost all non–ECG-gated multidetector chest CT studies. This review will discuss the available evidence on different measurements of left ventricular size obtained on non–ECG-gated CT of the chest. Measurement thresholds, technical issues, and...

Quantitative Computed Tomography Metrics From the Transplanted Lung can Predict Forced Expiratory Volume in the First Second After Lung Transplantation
Conclusions: QCT metrics demonstrate stronger correlations with FEV1 and are better predictors of pulmonary function than SQS. SQS performs moderately well in bilateral LTx, but poorly on unilateral LTx. In unilateral LTx, QCT metrics from the transplanted lung are better predictors of FEV1 than QCT metrics from the nontransplanted lung. (Source: Journal of Thoracic Imaging)

Short-term Automated Quantification of Radiologic Changes in the Characterization of Idiopathic Pulmonary Fibrosis Versus Nonspecific Interstitial Pneumonia and Prediction of Long-term Survival
Purpose: Fibrotic interstitial lung diseases presenting with nonspecific and overlapping radiologic findings may be difficult to diagnose without surgical biopsy.

The tridimensional geometry of the proximal femur should determine the design of cementless femoral stem in total hip arthroplasty
AbstractPurposeUsing a cementless femoral stem in total hip arthroplasty (THA), optimal filling of the proximal femoral metaphyseal volume (PFMV) and restoration of the extramedullary proximal femoral (PF) parameters (i.e., femoral offset (FO), neck length (FNL), and head height (FHH)) constitute key goals for optimal hip biomechanics, functional outcome, and THA survivorship. However, almost 30% of mismatch between the PF anatomy and implant geometry of the most widely implanted non-modular cementless femoral stem has been demonstrated in a computed tomography scan (CT scan) study. Therefore, this anatomic study aimed to ...

Liquid Exfoliation of Colloidal Rhenium Disulfide Nanosheets as a Multifunctional Theranostic Agent for In Vivo Photoacoustic/CT Imaging and Photothermal Therapy
Abstract Near‐infrared light‐mediated theranostic agents with superior tissue penetration and minimal invasion have captivated researchers in cancer research in the past decade. Herein, a probe sonication‐assisted liquid exfoliation approach for scalable and continual synthesis of colloidal rhenium disulfide nanosheets, which is further explored as theranostic agents for cancer diagnosis and therapy, is reported.

Percutaneous Instrumentation and Reduction Technique for the Treatment of Thoracolumbar Fractures: A Case Report
This article describes a new percutaneous method of thoracolumbar fracture reduction based on the 6-screw construct, which promotes an indirect reduction of the fractured vertebrae with lordotic rods connected with 4 long monoaxial percutaneous pedicle screws in the fractured and upper adjacent vertebrae. The vertebra below the fractured one is instrumented with polyaxial screws to facilitate the introduction of the lordotic rods. The postoperative radiography and computed tomography imaging results show that this technique is able to correct posttraumatic kyphosis and provide a solid and durable construct. (Source: Techni...

Recent Advances and Trends in Pediatric Cardiac Imaging
AbstractCardiac imaging is central to today ’s pediatric cardiology practice not only to diagnose structural congenital defects and delineate cardiac and extracardiac anatomy but also for determining the hemodynamic impact of the structural defects and acquired pediatric diseases. Not so long ago, clinicians had to heavily rely on angiograp hy as the main cardiac imaging modality to visualize the heart. Particularly, the development of echocardiography in the 1970s and 1980s together with the development of magnetic resonance imaging (MRI) and computed tomography (CT) resulted in a non-invasive diagnostic revolution ...

Microvascular decompression (MVD) allows immediate and long-term pain relief. Preoperative evaluation includes MRI (magnetic resonance imaging) and/or MRA (magnetic resonance angiography) of the brain. Having a pacemaker is a contraindication for MRI.
