Purpose: To describe the MR findings following cryoablation of long bones.
Materials And Method: Cryoablation was performed in femoral and tibial bones of 24 sheep under general anesthesia. MRI of the treated and untreated contralateral bones was performed immediately thereafter and at 2, 4 and 6 months after the cryosurgical procedure.
Results: On the MRI performed immediately after cryotherapy, the lesions showed low signal intensities relative to the normal bone marrow on unenhanced T1- and T2-weighted images. At 2, 4 and 6 months after cryoablation, the lesions showed high signal intensities on STIR images, low signal intensities on T1-weighted and heterogeneous enhancement on contrast-enhanced T1-weighted MR images. The femoral lesions decreased in size from 31 +/- 3 mm immediately after the cryotherapy to 13 +/- 4 mm 6 month later and the tibial lesions from 29 +/- 7 mm to 19 +/- 4 mm.
Conclusion: MRI shows bone marrow lesions immediately after cryotherapy and can easily monitor healing lesions. MR imaging is suitable for following cryotherapy.

Objective: The leptomeningeal ivy sign is a distinctive finding of moyamoya disease (MMD), characterized by a linear high signal intensity along the cortical sulci on contrast-enhanced T1 magnetic resonance imaging (MRI) and fluid-attenuated inversion-recovery MRI. We recently identified a similar linear enhancement along the cortical sulci using gadolinium-enhanced vessel wall MRI (VWMR) in patients with MMD. The aim of this study was to introduce the concept of the "VWMR ivy sign (VIS)".

Aims: WNT signalling pathway dysregulation is often a critical early component in colorectal neoplasia, particularly the chromosomal instability pathway. Using two WNT reporters, and , we sought to assess whether these polyps demonstrate predictable expression patterns and if these patterns show diagnostic value.
Methods: We evaluated 23 adenomas (TA), 23 sessile serrated lesions (SSLs), 14 SSL with dysplasia and 38 traditional serrated adenomas (TSA).

Background: The concentration of natural gas components significantly impacts the transportation, storage, and utilization of natural gas. Consequently, implementing online monitoring and leak detection systems is vital to guarantee the efficient use of natural gas and to uphold its safe and stable operation. Raman spectroscopy offers distinctive benefits, including high selectivity, superior precision, and the capability to detect multiple gas components simultaneously using a single-wavelength laser.

Background: Glycholic acid (GCA) can dynamically reflect the process of liver injury, and can be used for early diagnosis and curative effect evaluation of early hepatitis and cirrhosis. The highly sensitive detection of liver injury markers is conducive to a more accurate and effective auxiliary diagnosis of liver diseases. In addition, the low trigger potential helps to avoid more chemical interference and improve the detection sensitivity.

Miniaturized optical emission spectrometric (OES) devices based on various microplasma excitation sources provide a reliable tool for in-situ elemental analysis. The key to improving analytical performance is enhancing the excitation capability of the microplasma source in these devices. Here, dielectric barrier discharge (DBD) and point discharge (PD) technologies are combined to construct an enhanced dual-stage excitation source (called DBD-PD), which improves the overall excitation efficiency and OES signal sensitivity.
