Summary: This study aimed to characterize the ADC values of benign, malignant chondrogenic, and malignant non-chondrogenic bone tumors through diffusion-weighted imaging. Results showed significant differences in ADC values among these tumors, improving diagnostic accuracy for bone tumors.

Summary: This study describes the diffusion-weighted MRI measurements of 22 cases of spontaneous canine cerebrovascular accident (CVA). The results show that the median ADC values in normal control tissues and CVAs were less than 1.0x10(-3) mm(2)/s. There was a good correlation between absolute and relative ADC values in CVAs. Some lesions exhibited reduced absolute ADC values but relatively unchanged relative ADC values compared to matched normal contralateral tissue. CVAs with large hemorrhagic components did not show restricted diffusion.

Summary: The study demonstrated that high b-value ADC evaluation can help stratify molecular glioma subgroups, such as IDH-mutant and IDH-wildtype astrocytoma, as well as 1p/19q-codeleted oligodendroglioma, potentially with clinical implications.

Summary: This study aimed to identify the preoperative MRI findings of breast cancer in different molecular subtypes using DCE-MRI and DWI. It found significant differences in clinical and MRI features among the subtypes, with DWI ADC values providing biological clues about molecular subtypes, particularly in relation to axillary lymph node status.

Summary: The study found that RSI technology can differentiate between benign and malignant breast lesions, and is associated with prognostic factors for breast cancer. RSI-derived parameters can help in the differentiation of breast cancer, and combining them with ADC improves diagnostic performance.

Summary: This study demonstrates the correlation between the apparent diffusion coefficient (ADC) of diffusion-weighted images and potentially malignant prostate lesions. It also shows that the ratio of ADC and prostate-specific antigen density (PSAD), or ADC/PSAD, can be used as a better biomarker. Threshold values were determined to distinguish between histological cancer grades, reducing unnecessary biopsies.

Summary: This study aimed to determine the value of multiparametric MRI in the preoperative differential diagnosis of parotid tumors. The results showed significant differences in T2WI and ADC in the differentiation of benign and malignant tumors. Multiparametric MRI had a sensitivity, specificity, and accuracy of 81.8%, 88.6%, and 92.3%, respectively. The combination of multiparametric and conventional MRI improved the preoperative differential diagnosis of parotid gland tumors.

Summary: This study aimed to compare the diagnostic performance and utility of Diffusion Weighted MR Imaging (DWI) against routine Magnetic Resonance Imaging (MRI) for evaluating tendon injuries in the ankle and foot. The results showed that DWI had higher sensitivity and specificity than MRI in visualizing tendon injuries, providing more beneficial and diagnostic information.

Summary: The study assessed the impact of adding synthetic b-values to DWI for tumor visibility and breast cancer detection. Results showed that synthetic b-values 1200-1500 s/mm(2) were preferred for lesion conspicuity, especially in dense breast tissue. DWI was more specific but less sensitive and accurate than DCE-MRI for breast cancer detection.

Summary: The study aimed to assess whether the combination of DWI and T2WI can improve the diagnostic ability for distinguishing lung cancer from benign pulmonary nodules and masses. The optimal cut-off values for ADC and T2 CR were determined for accurate differential diagnosis. The combined assessment of DWI and T2WI showed higher sensitivity and accuracy in identifying PNMs, making it valuable for differential diagnosis.

Summary: The study demonstrates that by filtering or weighting individual acquisitions, the contrast for cancer can be enhanced, leading to increased sensitivity and reduced false positive rate. Motion-induced signal loss makes conventional signal-averaging suboptimal, potentially obscuring signals from areas with restricted diffusion.
