Article Synopsis
- - The study investigated immediate hypersensitivity reactions (IH) to iodinated and gadolinium-based contrast media (ICM; GBCM), focusing on differentiating between allergic and non-allergic responses, which is crucial for future medical treatment decisions.
- - Over 245 patients were analyzed through skin tests and other clinical evaluations, revealing an allergic reaction rate of 19.6% for ICM and 27.8% for GBCM, with notable cross-reactivity among patients.
- - The findings indicated that allergic IH was linked to more severe reactions and quicker onset than non-allergic IH, highlighting the need for more sensitive skin testing methods to better identify allergic responses to contrast agents.
Purpose: To evaluate the potential of iterative reconstruction for reducing the dose given to the patient during abdominal CT scanning.
Materials And Methods: A double abdominal CT scan acquisition (Somatom Definition AS+ Siemens) performed without contrast administration at -30% and at -70% of the doses (mAs) was compared to the standard acquisition in 10 patients. The raw data were reconstructed by filtered back projection (FBP) and using the SAFIRE iterative reconstruction method (five levels of iteration).
Internal models serve sensory processing, sensorimotor integration and motor control. They could be a way to construct and update a sense of verticality, by combining vestibular and somatosensory graviception. We tested this hypothesis by investigating self-orientation relative to gravity in 39 normal subjects and in subjects with various somatosensory losses showing either a complete deafferentation of trunk and lower limbs (14 paraplegic patients after complete traumatic spinal cord injury) or a gradient in the degree of a hemibody sensory loss (23 hemiplegic patients after stroke).

Materials And Methods: Patients having presented clinical signs of immediate hypersensitivity suggesting allergy after iodinated contrast medium were investigated. Histamine and tryptase concentrations were measured, and/or skin tests were performed.
