Association of apparent diffusion coefficient with Ki-67 proliferation index, progesterone-receptor status and various histopathological parameters, and its utility in predicting the high grade in meningiomas.
l;i S Abstract BACKGROUND: Accurate preoperative determination of the histological grade and cellular proliferative potential of meningioma by non-invasive imaging is of paramount importance. PURPOSE: To evaluate the utility of apparent diffusion coefficient (ADC) in determining the histological grade of meningioma, and to investigate the correlation of ADC with Ki-67 proliferation index (PI), progesterone receptor (PR) status, and a number of other histopathological parameters. MATERIAL AND METHODS: Histopathologically confirmed 94 meningioma patients (72 low-grade, 22 high-grade) who had undergone preo...

The effect of computed tomography on oxidative stress level and some antioxidant parameters.
CONCLUSION: CT, which is a widely used X-ray imaging technique and has numerous known side effects, was found to increase the levels of MDA, which is an indicator of oxidative stress, and to decrease the levels of some antioxidants including GSH, SOD, and CAT.

Quantitative T1 mapping of the substantia nigra using phase-sensitive inversion recovery sequence at 3.0-T: a healthy volunteer study.
CONCLUSION: In healthy adults, the area and T1 value of the SN measured on PSIR images were different from those obtained from NM images. This suggests that PSIR imaging may help in the assessment of SN degeneration. PMID: 32380909 [PubMed - as supplied by publisher] (Source: Acta Radiologica)

Imaging appearance of post-arthroscopic radiocarpal chondrolysis: comparison with osteoarthritis associated with scapholunate dissociation.
Abstract BACKGROUND: Since the diagnosis of post-arthroscopic chondrolysis is very difficult, it can be underdiagnosed and confused with other diseases in clinical practice. PURPOSE: To propose imaging features of post-arthroscopic radiocarpal chondrolysis (PRCC) and to compare these with osteoarthritis associated with scapholunate dissociation which are the most common misdiagnoses of PRCC. MATERIAL AND METHODS: To identify missed diagnoses of PRCC, 994 magnetic resonance imaging scans performed in 910 patients were retrospectively reviewed. After the identification of 73 patients who exhibited signific...

Differentiation between non-hypervascular pancreatic neuroendocrine tumors and mass-forming pancreatitis using contrast-enhanced computed tomography.
Abstract BACKGROUND: Non-hypervascular pancreatic neuroendocrine tumors (PNETs) showed slight or iso-enhancement in contrast-enhanced computed tomography (CE-CT), which shared similar imaging findings with mass-forming pancreatitis (MFPs). PURPOSE: To explore the value of CT imaging features in differentiating the two diseases. MATERIAL AND METHODS: Fifty-one patients with histologically proved MFPs (n = 27) or non-hypervascular PNETs (n = 24) were included. Two radiologists reviewed CT imaging findings and clinical features. Logistic regression analysis was performed to ident...

Evaluation of toxicity of gadolinium-based contrast agents on neuronal cells.
Abstract BACKGROUND: Gadolinium-based contrast agents (GBCAs) are widely used in magnetic resonance imaging (MRI). Recently, increased signal intensity has been reported in specific brain areas after repeated administrations of GBCAs. PURPOSE: To investigate the toxic effects of GBCAs on neuronal cells by using SH-SY5Y neuroblastoma cell cultures. MATERIAL AND METHODS: For toxicity assays, SH-SY5Y cells were incubated with different doses (0-1000 µM) of several macrocyclic (gadoterate meglumine and gadobutrol) and linear GBCAs (gadoversetamide, gadopentetate dimeglumine, gadodiamide, and gadoxetate...
