　　Emission computed tomography, abbreviated ECT imaging is a safe, non-invasive diagnostic method and being referred to as "functional imaging" due to its capability which can show both viscera anatomical morphology and functional changes. ECT imaging can provide earlier clues for diagnosis and nature or severity/extent of diseases. The department of nuclear medicine of Tianjin chest hospital aims to offer more comprehensive, definite, accurate and timely messages in support of diagnosis or prognosis for cardiovascular, respiratory, kidney and thyroid diseases in order to facilitate and optimize the therapeutic regimen. Symbia T6 (SIEMENS, Germany) is one of the latest/advanced type of SPECT/CT equipments which can integrate SPECT and CT examination and then produces combined images at the same fusion. So it Can maximize the functions of nuclear medicine imaging and radiology anatomical imaging and amplify the advantages of the two kinds of complementary imaging diagnostic information.

　　The following inspection and treatment programs are expected to carry out on basis of our clinical features.

　　(Ⅰ) Nuclear cardiology

　　1. Myocardial perfusion imaging(MPI)

　　(1) ischemic identification: to confirm myocardial ischemia and evaluate ischemic extent/severity in terms of rest and stress MPI.(2) Discrimination of viable myocardium: the Nitroglyceride combined with Dobutamine intervention trials will be applied to patients with impaired rest MPI to quantify the viable myocardium to guide the further regimen about whether revascularization or pharmacotherapeutics.

　　2. Gated myocardial perfusion imaging(G-MPI)

　　(1)To measure the chamber size and systolic function of left ventricles under rest/stress state.(2)To detect the wall motion and wall thickening rate of left ventricles.(3) Accurately evaluate the mechanical synchrony of left ventricular contraction by phase analysis.

　　(Ⅱ) Respiratory Nuclear Medicine

　　 1. Pulmonary perfusion / ventilation imaging (1)Diagnosis for pulmonary thrombus and the therapeutic evaluation. (2)Foresee the safety, feasibility of lung volume reduction surgery and predict the residual pulmonary function.

　　2.Radionuclide whole body bone imaging: to judge the incidence of bone metastases from lung cancer cohort.

　　3. ⁸⁹Sr therapy: ⁸⁹Sr is used for patients who have bone metastases.

　　(Ⅲ) Kidney Nuclear Medicine

　　1.To evaluate the blood perfusion and gathering, elimination function of kidney.

　　2.To detect the glomerular filtration rate(GFR) of each kidney definitely.

　　3.For diagnose of renal vascular hypertension.

　　(Ⅳ) Endocrine Nuclear Medicine

　　1. thyroid aspects :To recognize the size, location, morphous ,function of thyroid or ectopic thyroid; diagnose thyroiditis and thyrocele; judge the benign or malignant thyroid nodules; antidiastole diffuse or nodular goiter; measure iodine uptake to underlie ¹³¹I internal radiotherapy .

　　2. Provide parathyroid imaging for diagnosis of parathyroid diseases.
