As a non-invasive imaging modality,cardiac magnetic resonance(CMR)enables a"one-stop"in vivo assessment of cardiac morphology,structure,functional status and histological features,plays an irreplaceable role in the diagnosis,prognosis and risk stratification of cardiovascular diseases.In 2024,CMR has made continuous progress towards precision medicine.Upgraded technologies such as tissue characterization imaging and myocardial strain analysis,are gradually transformed into standard clinical practice.Artificial intelligence and other new algorithms have improved the quality and efficiency of CMR.The application of CMR in non-ischemic heart disease,ischemic heart disease and other areas is highly valued in the new version of various guidelines,highlighting the importance of CMR in the clinical management of cardiovascular diseases.This article aims to systematically review representative achievements of CMR in 2024 from the perspectives of both technological innovation and clinical translation,providing the latest update in this field.

Objective To investigate the antitumor mechanism of astragaloside combine with cetuximab on the colon cancer cell line RKO of EGFR over expression through cell proliferation and autophagy. Methods The cell proliferation of colon cancer cell line RKO intervened by astragaloside with or without cetuximab was detected by 4- methyl- teerazolium (MTT). The expressive changes for protein of EGFR 、P62 and LC3 in RKO cells was detected by western bolt. Results MTT showed that 100 ug/mL astragaloside combined with 120 ug/mL cetuximab had significantly inhibiting effect on RKO cells of EGFR expression. Western blot showed that astragaloside can affect the expression of P62 and LC3 to suppress the occurrence ofautophagy. Conclusion In the vitro studies showed that astragalosidecan enhance the antitumor cell proliferation of cetuximab through inhibit autophagy in the treatment of colon cancer.
