Urinary tract infection (UTI) is most common bacterial infection in childhood, and it may be the first symptom of congenital anomaly of the kidneys and urinary tract (CAKUT) in 30% of children. Prompt diagnosis and treatment are important for the prevention of acute complications as well as renal scarring

Idiopathic pulmonary hemosiderosis (IPH) extremely rarely occurrs in adults according to current literature.We report one case of IPH in a middle-aged woman presenting with extensive central-predominant ground glass opacities and consolidation in the lungs. Since these imaging findings are not specific and can be similar to other diffuse pulmonary diseases, it is essential to have an deep understanding of this disorder. Imaging findings must be combined with clinical laboratory examination to make a diagnosis of IPH. Transbronchial lung biopsy (TBLB) is the gold standard for evaluation of suspected patients. We review the current literature and provide a recommendation based on discussion.

This study aims at describing the CT imaging findings and role of multidetector computed tomography (MDCT) in evaluation of squamous cell carcinoma of buccal mucosa and its staging. The imaging findings in squamous cell carcinoma (SCC) of the oral cavity allow the radiologist to accurately determine the extent and staging of disease thereby help clinicians plan appropriate treatment.

Neurological impairments associated with Covid-19 have been the subject of numerous investigations since the end of 2019, when the SARS-CoV-2 virus appeared and showed a staggering rise worldwide. Neuroimaging in patients infected with Covid-19 revealed the apparition of severe brain pathologies, such as acute perfusion deficits and white matter abnormalities, meningeal enhancement, basal ganglia lesions, intracranial hemorrhage, encephalitis, cerebral venous thrombosis, encephalopathy, and stroke [1,2].

Adenoid cystic carcinoma (ACC) is a rare epithelial neoplasm, that may affect the salivary glands. It comprises 30% of epithelial minor salivary gland tumors. We present the case of a 56-year-old non-smoking woman with no significant medical history. The MRI finds a lesional process involving the right hemi mandible, the right buccal floor, which extends towards the region of the masticators and infiltrates the submandibular gland. A bone biopsy of the mandible under general anesthesia was performed, showing an adenoid cystic carcinoma. After announcing the diagnosis to the patient, she refused any treatment

Teamwork has been a recent focus of radiology literature on multidisciplinary and intradepartmental levels. Several publications discuss team building roles and daily checklist utilization. The overall endpoints of these studies vary; however, the theme is to improve workflow, patient safety, problem-solving, and department morale.

Undetected colonic polyps are considered a major cause of interval cancer of the colon. The Automatic Polyp Detection System (APDS) (Magentiq Eye LTD, Haifa, Israel) was developed to enhance the ability of endoscopists to detect polyps during screening colonoscopy. It is designed to be used both in real-time and offline. APDS runs directly on the video output of the endoscopic camera and highlights the polyp on the screen. APDS utilizes the power of Deep Learning and Computer Vision in order to improve polyp detection rates thus improving the performance of the endoscopist.

Giant cell arteritis (GCA) requires prompt diagnosis as clinical indicators of GCA are non-specific. Temporal artery biopsy (TAB) can be inconclusive and difficult to arrange timely. MR imaging is accurate for showing vessel thickening. However, the availability of MRI remains an issue in many radiology departments.

Adrenal incidentalomas (AIs) are frequent and although most of them are asymptomatic and benign, some do need treatment. The AIs follow-up has to be as sharp as to avoid missing pathology and to avoid harm and anxiety induced by the follow-up itself. It is, thus, a delicate medical condition for endocrinologists worldwide.

The focus of this research is aimed specifically at the application of near-infrared spectroscopy (NIRS) in exercise and sport science. NIRS is able to monitor the performance of muscle and cerebral tissue and evaluate their role during physical activity. By monitoring tissue oxygenation, an NIRS device is useful in several areas, which may benefit from its applications.

Murine osteoarthritis (OA) models are important for exploring OA pathology and treatment in the pre-clinical study. Longitudinal in vivo imaging modalities, including X-ray, computed tomography, and magnetic resonance imaging, are commonly used diagnostic tools in OA clinic, while end-point histomorphometry analysis is the major outcome measurement in the pre-clinical study because clinical imaging modalities have limited resolution for small animals.

Self-organized anodic porous alumina films with hexagonal pore lattice have attracted a considerable attention for biological arrays and confinement of various organic probes dyes in solutions. A molecular structure with axial symmetry in bis-heterocyclic indole chains and conjugate system, such as cyanine fluorophore Cy3 dye, was investigated here with respect to its fluorescence when loaded in the anodic alumina pores.

Human odor detection technologies have drawn attention due to the wide possibility of potential applications they open up in areas such as biometrics, criminal investigation and forensics, search for survivors under rubble, and security checkpoint screening. Gas chromatography/mass spectrometry (GC/MS) has been the most successful and powerful analytical approach developed to date for human odor analysis, and hundreds of human odorants have been identified using this tool.

The collection of human odor volatiles is of interest to forensic applications as a path to investigate canine scent discriminations in legal investigations. A study using a selected array of previously identified human odor compounds has been conducted to determine the retention and release capabilities of five (5) natural and synthetic fabric types, cotton (mercerized fabric and gauze matrix), polyester, rayon and wool.
