Combined PET/CT has been in existence clinically for nearly 7 years since development and initial evaluation from 1998 to 2001. Combined PET/CT offers advantages over PET and CT acquired on separate devices, including consolidation of imaging studies, more accurate data coregistration, improved lesion localization, and benefits related to radiation therapy planning. This article discusses CT and PET protocols pertinent to PET/CT imaging in patients who have head and neck cancer, including a discussion of how the CT portion of a PET/CT scan can be performed and a description of common PET/CT artifacts that may be encountered secondary to CT protocols.

Background: In pancreatic surgery Postoperative pancreatic fistula (POPF) represents the most dreaded complication, for which pancreatic texture is acknowledged as one of the strongest predictors. No consensual objective reference has been defined to evaluate the pancreas composition. The presented study aimed to mine histology data of the pancreatic tissue composition with AI assist and correlate it with clinic-pathological parameters derived from the RECOPANC study.

Background: Voice analysis has emerged as a potential biomarker for mood state detection and monitoring in bipolar disorder (BD). The systematic review aimed to summarize the evidence for voice analysis applications in BD, examining (1) the predictive validity of voice quality outcomes for mood state detection, and (2) the correlation between voice parameters and clinical symptom scales.
Methods: A PubMed, Scopus, and Cochrane Library search was carried out by two investigators for publications investigating voice quality in BD according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statements.

The anterolateral thigh (ALT) flap is a commonly used donor site for free tissue transfer, especially in head and neck reconstructions. The flap's success is primarily determined by the quality and quantity of its perforating vessels, which is why clinicians typically prefer harvesting from a healthy leg with intact vascular anatomy. Poliomyelitis typically causes unilateral lower limb paralysis, resulting in muscle atrophy and deformities.

The cases of head and neck cancer among persons with intellectual disability (PWID) are infrequently reported and therefore poorly understood. PWID often face increased barriers of access to healthcare, which can be further compounded when faced with a cancer diagnosis. This report presents the case of a 34-year-old Chinese female patient with Rett syndrome and intellectual disability, presenting with two primary cancers of the tongue and the trachea.
