A knowledge of the complex phenomena that regulate T1 signal on Magnetic Resonance Imaging is essential in clinical practice for a more effective characterization of pathological processes. The authors review the physical basis of T1 Relaxation Time and the fundamental aspects of physics and chemistry that can influence this parameter. The main substances (water, fat, macromolecules, methemoglobin, melanin, Gadolinium, calcium) that influence T1 and the different MRI acquisition techniques that can be applied to enhance their presence in diagnostic images are then evaluated.
View Article and Find Full Text PDFThe testis is a richly vascularized organ supplied by low-flow thin caliber vessels that are only partially detected by traditional Doppler systems, such as color and power Doppler. However, in the vascular representation, these techniques determine, albeit to different extents, a cut of the weak vessels due to the necessary application of wall filters that cut the disturbing frequencies responsible for artifacts generated by pulsations of the vascular walls and surrounding tissues. These filters cut a specific range of disturbing frequencies, regardless of whether they may be generated by low-flow vessels.
View Article and Find Full Text PDFPurpose: To identify new factors associated with hemorrhagic transformation (HT) despite early recanalization in patients with acute ischemic stroke treated with mechanical thrombectomy.
Methods: We retrospectively included patients with known onset of large vessel occlusion treated with mechanical thrombectomy +/- intravenous thrombolysis. Non-contrast CT was performed at 24 +/- 12 h from endovascular procedure.
Article Synopsis
- Paraneoplastic neurological syndromes (PNSs) are linked to cancer and involve the presence of specific antibodies that target neuron components, affecting the central nervous system (CNS).
- This study analyzed 26 cases of probable CNS-PNS over seven years, highlighting the varied clinical presentations and the importance of identifying the condition early for better treatment outcomes.
- The findings reinforce the need for routine screening for hidden cancers in patients showing CNS symptoms and suggest that initiating treatment promptly can help improve results, even in later diagnoses.
Objective: Prediction of fragility fractures in Cushing syndrome (CS) is a challenge since dual energy X-ray absorptiometry (DXA) measurement of bone mineral density (BMD) does not capture all the alterations in bone microstructure induced by glucocorticoid excess. In this study we investigated the relationship between trabecular bone score (TBS), bone marrow fat (BMF) and vertebral fractures (VFs) in endogenous CS.
Design: Cross-sectional.
