锝 [99mTc]亚甲基二膦酸盐注射液，适应症为主要用于全身或局部骨显像，诊断骨关节疾病、原发或转移性骨肿瘤病等。 本品为无色澄明液体。 主要用于全身或局部骨显像，诊断骨关节疾病、原发或转移性骨肿瘤病等。 成人静脉注射370～740MBq (10～20mCi) 99m Tc-MDP，2～3小时后显像，注射后嘱病人多饮水以加速清除非骨组织的显像剂。 取适合的体位检查，检查时应包括相对称的健康侧，以便与患侧作比较。 正常骨浓聚显像剂的量各部位不同，一般扁平骨较长骨显像 …

Oct 22, 2020 · Technetium-99m (99mTc) is an FDA-approved radionuclide agent for diagnostic imaging across various human organs, encompassing critical areas such as the brain, lungs, heart, and more. Following systemic administration, …

Technetium (99m Tc) medronic acid is a pharmaceutical product used in nuclear medicine to localize bone metastases [1] as well as other diseases that can alter the natural turn-over in the bone by bone scintigraphy.

Mar 29, 2007 · Imaging with 99m Tc-methylene diphosphonate (99m Tc-MDP) is the initial method of choice to detect skeletal metastases in cancer patients (9). For SPECT of the bone, metastable technetium (99m Tc) is tagged onto a phosphonate compound such as MDP to generate 99m Tc-MDP, which selectively concentrates in the bone.

Jan 6, 2022 · Technetium 99m-methyl diphosphonate (99mTc MDP) is a radiotracer used in nuclear medicine especially for bone scintigraphy. Any disease process which results in extracellular fluid expansion will lead to accumulation of this tracer.

Tc-99m是理想的医学示踪核素，在核医学诊断中应用很广泛，占全世界医疗用放射性元素的80%，其中90%用于扫描诊断。 Tc99m诊断体内出血部位：注射同位素后，用单光子断层扫描成像，连续扫描10-60分钟，如扫描阴性，则36小时内不同时间定时扫描，连续扫描中发现 ...

Quantitative measurement of bone using 99m Tc-methylene diphosphonate (99m Tc-MDP) provides global or local information of skeletal metabolism or transformation. In this paper, we make a brief review on the quantitative measurement of bone using 99m Tc-MDP and expect to provide guidance for clinical diagnosis and treatment.

Nov 23, 2023 · 锝，元素符号Tc，为银白色金属，原子序数为43，是首个以人工方法制得的元素。 锝总共有21种同位素，锝-99为最常见的同位素之一，而锝-99m，是锝-99激发态的同质异能核素，因为能量的不稳定而会发生 γ衰变 ，其在发射出γ射线后，会变回稳定态的锝-99。

Scintigraphy with technetium-99m methylene diphosphonate (MDP) delineates a wide spectrum of nonosseous disorders. Neoplastic, hormonal, inflammatory, ischemic, traumatic, excretory, and artifactual entities demonstrate abnormal soft-tissue uptake of Tc-99m MDP.

Dec 13, 2021 · Tc-99m是理想的医学示踪核素，在核医学诊断中应用很广泛，占全世界医疗用放射性元素的80%，其中90%用于扫描诊断。 Tc99m诊断体内出血部位：注射同位素后，用单光子断层扫描成像，连续扫描10-60分钟，如扫描阴性，则36小时内不同时间定时扫描，连续扫描中发现 ...
