Objective To evaluate the clinical practical value of the golden angle radial sparse parallel(GRASP)technology in the MR imaging quality of lung cancer under free-breathing state.Methods The imaging data of 30 lung cancer patients diagnosed with CT screening were collected by using a large-aperture 3.0T MR scanner.All patients underwent routine Cartesian breath-hold volume interpolation(BH-VIBE)scanning,then free-breathing dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)scanning based on GRASP technology,and another repetitive BH-VIBE scanning.The MR imaging quality was independently evaluated by two experienced thoracic radiologists including overall image quality,lesion outline,artifact grade and diagnostic confidence,mean-while,the CT images of the patient at the same time were used as a reference.The sequence information on MR images was also pro-cessed blindly.Results The GRASP sequence could effectively eliminate the interference of motion artifacts such as respiration and cardiac large vessel beats,and the image quality,lesion outline,artifact grade,and diagnostic confidence of the GRASP sequence were significantly better than the BH-VIBE(P＜0.01).The image quality of the GRASP sequence was more satisfactory with clea-rer tumor boundary and more details.Conclusion Free-breathing high-temporal-spatial resolution GRASP technology has better image quality than traditional BH-VIBE scanning,and it is a reliable method for high-resolution imaging of lung cancer.

ObjectiveTo observe the clinical effect of hand controlled rhythm music therapy on unilateral spatial neglect for stroke patients. MethodsFrom September, 2020 to September, 2022, 52 patients with unilateral spatial neglect after stroke in Wuxi Central Rehabilitation Hospital were randomly divided into control group (n = 26) and observation group (n = 26). Both groups accepted routine rehabilitation, and the observation group accepted hand controlled rhythm music therapy in addition, for eight weeks. Before and after treatment, the patients were assessed with Chinese Behavioral Inattention Test-Hong Kong version (CBIT-HK) routine tests (line crossing, letter cancellation, star cancellation, line bisection, figure and shape copying, and representational drawing) and modified Barthel Index (MBI). ResultsAfter treatment, six scores of CBIT-HK routine tests and the scores of MBI increased in both groups (|t| > 3.077, P < 0.05), and they were higher in the observation group than in the control group (|t| > 2.639, P < 0.05). ConclusionHand controlled rhythm music therapy could effectively alleviate the symptoms of unilateral spatial neglect after stroke, and improve the activities of daily living.
