"Doctor, is the nodule on my liver cancer?Do you want to go under the knife?”
Didn't I just finish the ultrasound?Why do I need to have an ultrasound?”
I've only heard of CT and MRI enhancements, and B-ultrasound enhancements?”
What exactly is contrast-enhanced ultrasound?”
Experts from the Second People's Hospital of Changde City said that contrast-enhanced ultrasound, also known as sonography or ultrasound enhancement, is an examination method that obtains blood flow information at the lesion on the basis of routine color ultrasound examination, after intravenous injection of ultrasound contrast agent, which is equivalent to coloring the lump, which can not only make the lump obvious, but also distinguish the nature of the lump according to the speed and specific way of the lump coloring.
The injection site is at the cubital fossa.
1. What are the advantages of contrast-enhanced ultrasound?
1.It can be displayed in real time and dynamically, and the entire blood perfusion process of the lesion can be observed, and it can be repeated**, which helps doctors to make a differential diagnosis of the lesion and find more small lesions.
2.It is safe, the ultrasound contrast agent does not need skin test, is discharged through the respiratory tract, has no liver and kidney toxicity, and is especially suitable for patients with liver and kidney insufficiency and liver and kidney organ transplantation. It is a new non-invasive, radiation-free ultrasound examination technique.
3.It's easy to use. The whole process can be completed in about 15-20 minutes.
2. Who needs hepatography?
1.Liver nodules incidentally found by conventional ultrasound;
2.Qualitative diagnosis of nodules after regular ultrasound monitoring in patients with chronic liver disease;
3.Diagnosis of cirrhosis of the liver and intrahepatic nodules and hepatocellular carcinoma;
4.Patients with impaired liver and kidney function who have contraindications to contrast-enhanced CT and MRI examinations;
5.Computed tomography (CT) and magnetic resonance imaging (MRI), cytology, or histology do not provide a definitive diagnosis and are not candidates for needle biopsy
6.Regular follow-up of intrahepatic nodules other than liver cancer;
7.Nodules that cannot be shown by ultrasound;
8.Postoperative evaluation of liver transplantation, preoperative examination of radiofrequency ablation of liver nodules, and judgment of efficacy after **.
3. Under what circumstances should hepatography not be done?
1.Patients with recent acute coronary syndrome or clinically unstable ischemic heart disease;
2.Patients with severe pulmonary hypertension (pulmonary hypertension 90mmHg), patients with uncontrolled systemic hypertension and **patients with respiratory distress syndrome;
3.Patients with acute heart failure, cardiac function class III, or severe cardiac rhythm disorders;
4.Those who are allergic to sulfur hexafluoride;
5.Contrast-enhanced ultrasound is not recommended for pregnant or lactating women unless it is particularly necessary.
4. What preparations do I need to make for hepatography?
Prepare the pre-imaging examination data to facilitate the comparison of changes in the lesion.
