China's medical device market shows promise despite slowdown

The market for medical devices in China still has great potential despite a recent slowdown in the segment's growth rate, according to a new report by China MedTech Marketing (CMTM). In this article, CMTM's Owen Tang explains how a projected decline in the growth rate isn't expected to dampen enthusiasm for medical devices, due to a variety of factors.

Imaging vendors target China's rural healthcare market

As China rushes to modernize its healthcare system, big cities such as Beijing and Shanghai have attracted most of the attention. But medical imaging vendors are now moving into China's vast countryside. Owen Tang of ChinaBionews offers a look at China's new frontier for growth.

MRI-based biomarker tool can predict progression to dementia

The tool measures gray matter shrinkage in the brain, predicting when mild cognitive impairment progresses to dementia.

Comparison of contrast-enhanced CT (ceCT) and FAPI-PET in detecting peritoneal carcinomatosis in patient with advanced ovarian carcinoma. (A) ceCT shows subtle peritoneal thickening that is difficult to delineate. (B) Maximum-intensity-projection image demonstrating diffuse intense FAPI uptake corresponding to extensive peritoneal carcinomatosis. (C) FAPI-PET shows intense uptake corresponding with peritoneal carcinomatosis, with improved lesion conspicuity over ceCT.

PET outperforms CT in ovarian cancer

Examples of ultrasound findings and techniques. (A) Images in a 39-year-old male patient with a mass in the left thigh. The mass is heterogeneous on the B-mode US image (compared with the patient in D) and showed increased microvascularity (superb microvascular imaging [SMI]) and shear-wave elastography (SWE) values. Undifferentiated pleomorphic sarcoma was diagnosed at biopsy (with pleomorphic rhabdomyosarcoma in surgical specimen). (B) Images in an 18-year-old male patient with a mass in the left leg. The mass is hypoechoic on the B-mode image, with no other findings suggestive of malignancy. The lesion is in contact with the cortex of the tibia, which is slightly irregular. CT revealed a doubtful anteromedial tibial erosion. The microvascular study demonstrated high vascularization, suggestive of malignancy. Periosteal Ewing sarcoma was diagnosed with both histologic and immunohistochemical confirmation. (C) Images in a 69-year-old female patient with a lump growing on the outside of the left leg. Multiple SWE examinations were performed (please note the high values obtained in the measurements, whereas the color map highlights the stiffness relative to adjacent tissues). SMI showed areas of increased vascularization to target for sampling. Undifferentiated spindle cell sarcoma was diagnosed at biopsy, with residual leiomyosarcoma in the surgical specimen after neoadjuvant therapy. (D) Images in a 56-year-old female patient with a mass in the right thigh. The mass is heterogeneous at both B-mode ultrasound (similar to patient A) and MRI (coronal T2-weighted spectral attenuated inversion recovery [SPAIR]; T1-weighted pre-contrast and postcontrast imaging), which even shows uptake after the administration of paramagnetic contrast material, which is traditionally suggestive of malignancy. Low values at SMI and elastography are suggestive of benignity. Spindle cell lipoma was diagnosed at biopsy, with atypical spindle cell lipomatous tumor in the surgical specimen.

PET outperforms CT in ovarian cancer

Peritoneal carcinomatosis in ovarian cancer is cancer that has spread from the ovaries to the peritoneum.

CT reveals progressive growth pattern in incidental lung nodules

This pattern is most associated with a family history of lung cancer.

August 25, 2026

Serial axial chest CT scans demonstrating the longitudinal evolution of small pure ground-glass nodules (pGGNs) incidentally detected during a routine wellness assessment. (A) Images in a 37-year-old woman with a family history of lung cancer show a nodule with the progressive growth pattern (box). The baseline CT scan, obtained in October 2017, demonstrates a pure ground-glass nodules in the right lower lobe. Consecutive CT scans obtained from 2017 to 2022 show the continuous enlargement of the nodule during active surveillance. The maximum diameter of the nodule increased from 5.6 mm in 2017 to 10.2 mm in 2022. (B) Images in a 45-year-old man show a nodule with the indolent growth pattern (box). The baseline CT scan, obtained in April 2018, demonstrates a pure ground-glass nodules in the left lower lobe. Consecutive CT scans obtained from 2019 to 2023 show that the nodule remained radiographically stable during CT surveillance. The maximum diameter of the nodule was 5.4 mm in 2018 and 6.1 mm at the final surveillance scan in 2023.
