Color Doppler and Microvascular Flow Imaging to Evaluate the Degree of Inflammation in a Case of Hidradenitis Suppurativa

Microvascular Flow Imaging is a new ultrasound technique with better ability than Color Doppler Imaging to identify small vessels that have slow blood flow, and it permits better evaluation of the features, especially microvascular architecture, of various lesions. We describe a case of inguinal hidradenitis suppurativa in a patient with positive risk factors (young age, female, smoker, and obese), diagnosed by ultrasonography using B-Mode, Color Doppler, and finally also with Microvascular Flow Imaging. Our aim is to demonstrate the usefulness of this new technique in characterization of lesions.

✓ “Color Doppler energy” (or “power Doppler”), a new color Doppler ultrasound technique that is independent of flow direction and very sensitive to movement, was assessed for its use in the identification of intracranial aneurysms in patients with recent subarachnoid hemorrhage immediately prior to using cerebral angiography. Features that identified aneurysms using this technique included the appearance of abnormal color where no normal artery was expected, abnormal bulging of an artery, and greater “expansibility” of the aneurysm in comparison to an adjacent normal vessel. In this exploratory study, 30 of 33 aneurysms were correctly identified in 35 patients with a good bone window. Color Doppler energy is considerably more sensitive to intracranial blood flow than conventional color Doppler imaging. Color Doppler energy is a useful research tool; if these preliminary results are verified in larger series, in addition to examination for vasospasm, the technique could be used for identification and follow up of aneurysms.

Purpose: Radiological findings were investigated in 6 cases of intrahepatic portal-hepatic venous shunt (IPHVS) without chronic liver disease. Material and Methods: Six patients with IPHVS were examined using US, CT and MR imaging. US was performed in all patients and color Doppler imaging in 5 patients. CT was performed after i.v. bolus injection of contrast medium in 4 patients. MR imaging and MR angiography were performed in one patient. Results: The shunt was present in the right lobe in 4 patients and in the left lobe in 2 patients. The shunts consisted of focally dilated or tubular vessels (1 aneurysmal) in 4 patients, and multiple small vessels in 2 patients. US revealed anechoic structures with various configurations at the shunt. Color Doppler imaging could detect blood flow in various directions in the shunt vessels in 5 patients. CT and MR images showed these abnormal vascular structures in the liver. MR angiography was also useful for evaluating the relationship between the portal and the hepatic veins. Conclusion: Color Doppler imaging was the best modality for evaluation of IPHVS.
