Dysfunctioning mechanical mitral valve prosthesis: When thrombus over pannus makes hinders diagnosis
Radiologia (Engl Ed). 2024 Jan-Feb;66(1):90-93. doi: 10.1016/j.rxeng.2022.11.008. Epub 2024 Jan 24.ABSTRACTProsthetic valve obstruction is a rare but potentially lethal complication. The most frequent causes are thrombus and pannus formation, in the absence of infectious data. Diagnosis is not always easy using cardiac CT scanning and in 46%-85% of cases thrombus and pannus coexist, complicating the diagnosis. A rapid diagnosis is essential to avoid a fatal outcome of this pathology whose mortality, despite correct treatment, is high.PMID:38365358 | DOI:10.1016/j.rxeng.2022.11.008 (Source: Radiologia)

Implementing a coronary CT angiography protocol based on the body mass index: Radiation dose reduction, image quality, and diagnostic performance
CONCLUSIONS: In the standard protocol, the radiologist selects higher kilovoltage for CT angiography studies for patients whose previous calcium score indicates the presence of coronary calcium. In the low-dose protocol, linking kilovoltage with body mass index enables the dose of radiation to be reduced by 65% while obtaining excellent or good image quality in 96% of studies and excellent diagnostic performance.PMID:38365351 | DOI:10.1016/j.rxeng.2022.01.004 (Source: Radiologia)

Role of intravoxel incoherent motion (IVIM) imaging in response assessment of hepatocellular carcinoma after transarterial chemoembolization (TACE) - A prospective study
CONCLUSION: IVIM imaging is feasible to assess the response in HCC after TACE. True diffusion is more sensitive and specific than apparent diffusion in evaluating the response.PMID:38365352 | DOI:10.1016/j.rxeng.2023.03.003 (Source: Radiologia)

Inflammatory lesions of the brainstem: Keys for the diagnosis by MRI
CONCLUSION: Inflammatory lesions involving the brainstem are associated with a wide range of autoimmune, infectious, and paraneoplastic syndromes, making the differential diagnosis complex. Being familiar with these entities, their clinical characteristics, and their manifestations on MRI, especially the number of lesions, their shape and extension, and their appearance in different sequences, is useful for orienting the radiological diagnosis.PMID:38365353 | DOI:10.1016/j.rxeng.2023.01.010 (Source: Radiologia)

Irreversible electroporation: Beyond the limits of tumor ablation
Radiologia (Engl Ed). 2024 Jan-Feb;66(1):47-56. doi: 10.1016/j.rxeng.2023.04.002. Epub 2023 Jun 26.ABSTRACTIrreversible Electroporation (IRE) is a non-thermal tumor ablation technique. High-voltage electrical pulses are applied between pairs of electrodes inserted around and/or inside a tumor. The generated electric current induces the creation of nanopores in the cell membrane, triggering apoptosis. As a result, IRE can be safely used in areas near delicate vascular structures where other thermal ablation methods are contraindicated. Currently, IRE has demonstrated to be a successful ablation technique for pancreatic, ren...

Update of cartilaginous tumours according to the WHO classification 2020
Radiologia (Engl Ed). 2024 Jan-Feb;66(1):57-69. doi: 10.1016/j.rxeng.2023.05.006. Epub 2024 Jan 12.ABSTRACTCartilaginous tumours are a large and heterogeneous group of neoplasms characterised by the presence of a chondroid matrix, with lobular growth and arcuate, ring-like or popcorn-like calcification patterns. MRI shows hyperintensity in T2-weighted sequences and a lobulated or septal relief in postcontrast images. In the WHO 2020 classification, chondral tumours are classified as benign, intermediate or malignant. Despite technological advances, they continue to pose a challenge for both the radiologist and the patholog...

Epub 2024 Jan 25.ABSTRACTThe universally accepted system for the transmission of scientific knowledge in the field of medicine has long been grounded in scientific publications. Social networks can be a useful alternative or complementary method of transmitting this knowledge. Social networks (e.g., Twitter, Instagram, Facebook, LinkedIn, YouTube, and TikTok) generate educational contents that enable quality training, despite their informality. Each of these networks has strengths and weaknesses that users should know about. These platforms a...

FLAIR hyperintensity in the subarachnoid space: Main differentials
Radiologia (Engl Ed). 2024 Jan-Feb;66(1):78-89. doi: 10.1016/j.rxeng.2022.01.003. Epub 2024 Jan 13.ABSTRACTThe fluid-attenuated inversion recovery (FLAIR) sequence forms part of the vast majority of current diagnostic protocols for brain MRI. This sequence enables the suppression of the signal from cerebrospinal fluid, facilitating the detection of disease involving the subarachnoid space. The causes of hyperintensity in the arachnoid space in this sequence can be divided into two main categories: hyperintensity due to disease and hyperintensity due to artifacts. Hyperintensity due to tumors, inflammation, vascular disease...
