CT exposure in adult and paediatric patients: A review of the mechanisms of damage, relative dose and consequent possible risks
Get PDFAn increase has been observed not only in the absolute number of CT examinations but also in the length of coverage and number of scanning phases, with the result that exposure to ionising radiation from CT is becoming an increasingly serious problem. The extent of the problem is not entirely known and cannot be adequately addressed without proper knowledge of all the phases that leads to the effective dose calculation. In light of the growing awareness of the issue of ionising radiation dose and the possible risk for the individual and the population, there is a need for radiologists, medical physicists and radiographers to play an active role in dose management. In this review, the authors try to delineate the problem in a consequential and multifaceted way: radiation–patient interaction, possible mechanisms of damage, main CT dose units, risk and its quantification in the population, with the aim of optimizing the acquisition dose without diagnostic drawbacks.

Despite its occurrence in various organs, a cCS is exceptionally rare in the skin, predominantly affecting older males. The etiology of a cCS is unclear, but it may originate from a single progenitor cell capable of dual differentiation or from a collision of carcinoma and sarcoma cells. Clinically, a cCS presents as a rapidly growing, painful, ulcerated nodule or plaque on sun-exposed skin, with a high risk of local invasion and metastasis. Histopathologically, a cCS includes various epithelial components, such as squamous cell carcinoma and basal cell carcinoma, along with undifferentiated sarcomatous components resembling atypical fibroxanthoma. The tumor may also exhibit heterologous differentiation like angiosarcomatous or rhabdomyosarcomatous features. We present three cases of a cCS, highlighting their clinical and histological characteristics and comparing them with previously reported cases. Understanding a cCS is complicated by its rarity and diverse presentation, emphasizing the need for further research to elucidate its pathogenesis and optimal management
Edema-like marrow signal intensity: a narrative review with a pictorial essay
Get PDFThe termedema-likemarrowsignal intensity (ELMSI) represents a general termdescribing an area of abnormal signal intensity atMRI. Its appearance includes absence of clear margins and the possibility of exceeding well-defined anatomical borders (forexample, physeal scars). We can define “ELMSI with unknown cause” an entity where the characteristic MR appearance isassociated with the absence of specific signs of an underlying condition.However, it ismore often an important finding indicatingthe presence of an underlying disease, and we describe this case as “ELMSI with known cause.” It presents a dynamic behaviorand its evolution can largely vary. It initially corresponds to an acute inflammatory response with edema, before being variablyreplaced by more permanent marrow remodeling changes such as fibrosis or myxomatous connective tissue that can occur overtime. It is important to study ELMSI variations over time in order to evaluate the activity state and therapeutic response of aninflammatory chronic joint disease, the resolution of a trauma, and the severity of an osteoarthritis. We propose a narrative reviewof the literature dealing with various subjects about this challenging topic that is imaging, temporal evolution, etiology, differentialdiagnoses, and possible organization, together with a pictorial essay
