Dual energy CT is a recent upgrade to this diagnostic imaging technique. The purpose of critical narrative review lay out the clinical applications Hounsfield Units and their variation across x-ray spectrum using DECT. We explore new reconstruction methods parametric maps helpful for diagnosis prevalent pathologies such as fatty liver disease, urolithiasis, identify complications after interven...

OBJECTIVE to evaluate the influence of Ki-67 and P16INK4a proteins immunohistochemical expressions on the clinical and morphological parameters of perioral squamous cell carcinoma induced with 9,10-dimethyl-1,2-benzanthracene (DMBA) in mice. METHODS we topically induced the lesions in the oral commissure of ten Swiss mice for 20 weeks, determining the time to tumors onset and the average tumo...

Transcription factors play a central role in the epithelial-mesenchymal transition (EMT), which is one of the biomolecular mechanisms involved in the progression of urothelial carcinomas of the bladder (UCB). In this study, we analyzed the immunoexpression of Twist 1, Snail, Slug and β-catenin in relation to histopathological prognostic parameters of UCB. The obtained results indicated the asso...

"Stereotactic" is an exact radiotherapy treatment modality which implements invasive and non-invasive facilities for improving precise dose delivery. Stereotactic refers to three-dimensional localization of a specific point in space by a unique set of coordinates that relate to a fixed external reference frame. An accurate delivery of radiation is attainable using these techniques with high pre...

The aim of the study was to evaluate the usefulness of elastography in the differential diagnosis of benign and malignant tumours of the mammary gland in dogs. The study was performed to 12 female dogs of different breeds aged 5-12 years in which tumoral lesions of the mammary gland were found in the clinical examination. In all the animals elastographic examination of the lesions was carried o...

Introduction: One of the most commonly used radiography methods for the diagnosis of oral and dental diseases is the panoramic radiography technique. This technique is widely used due to ease of implementation, extensive coverage, time and cost savings. Dental radiography, as a routine and appropriate test, accounts for about 33% of the total radiographic examination. However, ...

A 73 year-old male farm laborer from a rural area presented a 15 year history of extensive tumoral lesions over his left leg. Histological studies of skin biopsy showed pseudoepitheliomatous hyperplasia and granulomatous chronic inflammatory process with muriform cells, confirming chromoblastomycosis (CBM). Cladophialophora carrionii was isolated in culture. Treatment with itraconazole 400 mg/d...

CLINICAL CASE A 35-year-old man with a family history of von Hippel-Lindau disease was diagnosed to have two retinal hemangiomas in the right eye and another in the left eye. The hemangiomas were treated with cryotherapy and laser photocoagulation respectively. Despite apparent good resolution of the retinal lesions, progressive visual loss was observed. An MRI was then performed and showed bil...

The introduction of microbubble contrast agents (CA), which act as blood pool tracers, has overcome the limitations of conventional B-Mode, colour or power Doppler ultrasound, enabling the display of parenchymal microvasculature. Initially, the use of CA was accepted for hepatic lesions. In the following years, experts have expanded recommendations, as a result of the method's efficiency in ext...

Evaluation of calcified metastatic lesions by conventional imaging can be challenging. Ovarian cancer metastases can present with calcification which might increase in size and number following therapy. It is not entirely clear whether these calcifications are associated with tumor response or disease progression. Calcified lesions which do not change in size or configuration are particularly p...
