Summary: To correctly identify intracranial hemorrhage (ICH) and distinguish it from other lesions, it is necessary to understand the imaging characteristics of ICH on susceptibility weighted imaging (SWI). It is a common misconception that blood appears as a black signal on SWI, but the appearance of ICH on SWI varies at different stages. Additionally, a low signal on SWI does not always indicate the presence of blood products. This review discusses and illustrates the appearance of ICH on SWI at all stages and common causes of a low signal on SWI.

Summary: This study discussed the value of susceptibility-weighted imaging (SWI) in evaluating the ischemic penumbra of patients with acute cerebral ischemic stroke, finding a high consistency in the ischemic penumbra through SWI-DWI and PWI-DWI mismatches. The SWI-DWI mismatch can aid in preventing the injection of contrast agents and accurately diagnosing the acute stroke ischemic penumbra.

Summary: Quantitative parameters derived from diffusion kurtosis imaging (DKI) and intravoxel incoherent motion (IVIM) are valuable in differentiating histologic grades and clinical stages of clear cell renal cell carcinoma (ccRCC). Diffusion coefficient (D) and mean diffusivity (MD) values have better diagnostic performance in grading and staging ccRCC. Combined IVIM and DKI parameters show slightly enhanced diagnostic efficacy.

Summary: The study explored the role of MRI texture analysis based on SWI in predicting the Fuhrman grade of ccRCC, with the developed SWI-based texture model showing reliable quantitative ability to differentiate high-grade from low-grade ccRCC. The SWI-based texture model had a high area under the ROC curve of 0.81, with 80% accuracy, and could potentially be used for preoperative assessment and decision-making in surgical treatment of ccRCC.

Summary: This study compares the value of different imaging techniques in evaluating the histological grade of cervical squamous carcinoma (CSC). The results show that amide proton transfer-weighted imaging (APTWI) is more effective in identifying the histological grade of CSC compared to routine diffusion-weighted imaging (DWI) and diffusion kurtosis imaging (DKI). APTWI is recommended as a supplementary scan to routine DWI for CSCs.

Summary: Renal cell carcinoma is the sixth most common cancer in men and the ninth most common cancer in women, with prognosis closely related to metastasis. Nuclear medicine imaging, combining the sensitivity of radionuclides with the resolution of structural imaging, provides a more accurate and reliable approach for diagnosing, staging, prognosis prediction, and therapy response assessment in RCC.

Summary: This study investigated the association of MAPK cascade genes with renal cell carcinoma risk and survival, revealing that a specific single nucleotide polymorphism in the MAPK10 gene is linked to lower RCC risk and metastasis. High MAPK10 expression is associated with a favorable prognosis, and MAPK10 activation can inhibit RCC cell growth.

Summary: This study investigates the use of preoperative EOB-MRI-based radiomics to predict GPC3-positive expression and recurrence-free survival in patients with HCC < 5 cm. A comprehensive nomogram incorporating GPC3-oriented radiomics models is developed and found to outperform clinicoradiologic algorithms. The radiomics score is also found to be correlated with the histological GPC3-positive phenotype and survival outcomes.

Summary: This study aimed to explore the feasibility of pancreatic imaging at 5 T and evaluate the practical improvement of T2-weighted MRI and diffusion-weighted imaging (DWI) at 5 T as compared with 3 T. The results showed that imaging at 5 T provided higher image quality ratings and SNR compared to 3 T for both T2-weighted and DWI images. However, there were no significant differences in the mean ADC values and CV of ADC between 3 T and 5 T measurements.
