Advances in identifying the hypoxic status of malignant tumors with ^99mTc-HL91 scintigraphy

^99mTc-HL91 is a hypoxic agent and can be uptaken by hypoxic issues or cells of malignant tumors. It may be able to provide the information directly in detection of hypoxic status of tumors through imaging. It may be used not only in the early diagnosis of malignant tumors, but also in dynamic detection of hypoxic status of tumors. Thus significant information may be obtained for clinical diagnosis and treatment.
