To assess the diagnostic performance of multislice computed tomography (MS-CT) in the classification of atypical or complex cystic renal masses using the Bosniak system in comparison to contrast-enhanced ultrasound (CEUS) and, in unclear cases, to the surgery findings.Thirty-two consecutive patients (14 women, 18 men; age range 39-72 years) with 37 atypical or complex cystic renal masses at MS-CT underwent conventional ultrasound (US) and CEUS. CEUS employed a low-MI technique using 1.6-2.4 ml SonoVue (Bracco, Italy) i.v. and a 2-4 MHz multifrequency transducer (Siemens, Sequoia, Acuson). Fourteen masses were resected, the remaining 23 lesions were followed up for periods ranging from 3 months to 2 years. Images and digital cine clips of all lesions were evaluated by blinded readers. On the basis of MS-CT appearance the lesions were assigned to the Bosniak classification. Similar criteria modified for US imaging were used to score atypical cysts at CEUS.In the Bosniak classification at MS-CT the lesions were scored as category II (n = 15), IIF (n = 7), III (n = 8) and IV (n = 7). At CEUS, masses were classified as Bosniak classification II (n = 8), IIF (n = 12), III (n = 8) or IV (n = 9). All type IV and 6/8 type III and 1/8 type IIF lesions were removed surgically. All category IV and 3/8 category III lesions of the surgical group were malignant, the one type IIF lesion was benign. All class II and IIF cysts except one were stable after a follow-up period ranging from 3 months to 2 years. In 7/37 lesions (19%) the MS-CT and CEUS scores were different, while in 30/37 (81%) they were equivalent. CEUS depicted more thin septa than MS-CT, or upgraded wall thickness, resulting in a Bosniak score upgrade from category II to IIF in 5 lesions. Two cystic renal masses could not be clearly assigned by MS-CT but were considered malignant due to the additional information from CEUS, which was confirmed by surgical removal (small cystic renal cancer).CEUS with SonoVue allows an early evaluation of atypical or complex cystic renal masses. It is an additional examination to MS-CT. Due to the dynamic examination, additional information about perfusion of the cystic septa or cystic renal cancer can be gained.

“…Although second-generation ultrasound contrast has shown great accuracy in the detection of aortic endoprothesis abnormalities (endoleaks) [21,22], to our knowledge there is no article that describes its use in TIPS evaluation. The purpose of our study was, therefore, to compare the results obtained with venography to previous contrast-enhanced ultrasonography (CEUS) examination and to draw up CEUS criteria for dysfunction.…”

Intraductally applied contrast-enhanced ultrasound (IA-CEUS) for evaluating obstructive disease and secretory dysfunction of the salivary glands

Obstructive diseases of the salivary glands are a common problem, usually based on sialolithiasis, duct stenosis, foreign bodies or other more rare causes. Secretory dysfunction, often associated with Sjögren syndrome or post radiation treatment, is also a frequent problem. Several diagnostic tools exist to classify the disease; however conventional radiological imaging or ultrasound does not provide a diagnosis in 5-10% of all cases. Intraductally applied contrast-enhanced ultrasound (IA-CEUS) improves the visualization of obstructive diseases of the salivary glands. IA-CEUS is a promising tool for assessing the ductal system and to diagnose and characterize abnormalities. This study describes the assessment of IA-CEUS in diagnosing different obstructive and chronic inflammatory conditions of the salivary glands.
