Abstract Cancer is one of the leading causes morbidity and mortality. Imaging studies are central to initial staging follow-up management cancers. In past, oncologists have largely relied on anatomical imaging for staging, restaging, therapy monitoring. The introduction positron emission tomography-computed tomography (PET-CT) its availability has transformed practice cancer imaging. PET-CT an ...

conclusions most patients are referred for restaging and demonstrate evidence of regional or distant metastasis with significant value for further treatment planning. providing insurance coverage and familiarizing referring physicians about appropriate indications of this relatively new diagnostic modality will be to the best interest of head and neck cancer patients in long term. methods we re...

Gastric cancer accounts for approximately 8% of new cancers worldwide (Jemal et al., 2011). Early diagnosis and accurate preoperative staging are critical for improving outcomes, and this includes the identification of the tumor location, depth of invasion, lymph node status, and the presence of metastasis (Monig et al., 2002; Chen et al., 2007; Makino et al., 2011). Current methods for the det...

OBJECTIVE Patients with head and neck cancer frequently present to academic tertiary referral centers with imaging studies that have been performed and interpreted elsewhere. At our institution, these outside head and neck imaging studies undergo formal second opinion reporting by a fellowship-trained academic neuroradiologist with expertise in head and neck imaging. The purpose of this study w...

High-energy penetrating extremity injuries are often associated with severe open fractures that have varying degrees of soft-tissue contamination and tenuous soft-tissue coverage. The result is a relatively high prevalence of chronic osteomyelitis compared with that in civilian trauma patients. Diagnosing chronic osteomyelitis requires a careful history and thorough physical and radiographic ex...

Whole-body imaging in children was classically performed with radiography, positron-emission tomography, either combined or not with computed tomography, the latter with the disadvantage of exposure to ionizing radiation. Whole-body magnetic resonance imaging (MRI), in association with the recently developed metabolic and functional techniques such as diffusion-weighted imaging, has brought the...

Optical imaging enables real-time visualization of intrinsic and exogenous contrast within biological tissues. Applications in human medicine have demonstrated the power of fluorescence imaging to enhance visualization in dermatology, endoscopic procedures, and open surgery. Although few optical contrast agents are available for human medicine at this time, fluorescence imaging is proving to be...

The conventional low former résection with mechanical or manual colo-anal anastomosis is an alternative to the amputation abdomino-périnéale in cancers of the low rectum. The technique of résection inter-sphinctérienne, which includes the ablation of the sphincter intern, allows a conservation sphinctérienne for the rectal tumours juxta and intracanalaires. The néoadjuvants treatments facilitat...
