Liver haemangiomas undetermined at grey-scale ultrasound: contrast-enhancement patterns with SonoVue and pulse-inversion US.

2005

The objective of this study was to describe the spectrum of contrast-enhancement patterns of hepatic haemangiomas undetermined at grey-scale ultrasound (US) on SonoVue-enhanced pulse-inversion (PI) US. Twenty patients (11 women, nine men) with 35 haemangiomas (size range: 1-7 cm; mean: 3.1 cm) undetermined at baseline US underwent PI at low M.I. (0.05-0.08) after i.v. injection of SonoVue. All haemangiomas were confirmed by typical helical computed tomography (CT) and/or magnetic resonance imaging (MRI) findings. US examinations were videotaped and then reviewed by two experienced radiologists blinded to the final diagnosis. Readers evaluated by consensus the baseline echogenicity and the d…

Imaging of hepatic hemangioma: from A to Z

2019

The hemangioma is the most common solid lesion of the liver. Therefore, radiologists must know the typical and atypical imaging findings of this lesion in order to reach a correct diagnosis and avoid diagnostic errors. However, only few papers have comprehensively described the entire spectrum of atypical and uncommon imaging features. In this updated review, we provide the imaging features of hepatic hemangioma, in both typical and atypical forms, as well as its association with abnormalities in the adjacent hepatic parenchyma and other hepatic lesions, and its complications.

Coronary artery calcium score on low-dose computed tomography for lung cancer screening

2013

Aim: To evaluate the feasibility of coronary artery calcium score (CACS) on low-dose non-gated chest CT (ngCCT). Methods: Sixty consecutive individuals (30 males; 73 ± 7 years) scheduled for risk stratification by means of unenhanced ECG-triggered cardiac computed tomography (gCCT) underwent additional unenhanced ngCCT. All CT scans were performed on a 64-slice CT scanner (Somatom Sensation 64 Cardiac, Siemens, Germany). CACS was calculated using conventional methods/scores (Volume, Mass, Agatston) as previously described in literature. The CACS value obtained were compared. The Mayo Clinic classification was used to stratify cardiovascular risk based on Agatston CACS. Differences and corre…

Non invasive imaging of coronary arteries with 64-slice CT and 1.5T MRI: challenging invasive techniques

2007

Non-invasive coronary artery imaging challenges any diagnostic modality, because of the complex and tortuous anatomy and cardiac contraction and respiration. Therefore, non-invasive coronary imaging requires high spatial and temporal resolution. Our purpose is to discuss the feasible applications in coronary imaging of Magnetic Resonance Imaging and Multi-slice Computed Tomography (MSCT). Focus will be devoted to potential indications and clinical impact of MSCT because of the fast development and the important results recently reported, in particular with the recent introduction of 64-slice equipments. MSCT of the coronary arteries is a promising imaging modality for the assessment of coro…

IMAGING FINDINGS SYSTEMATIZATION AND IMAGING STAGING PROPOSAL IN BISPHOSPHONATES ASSOCIATED OSTEOMYLITIS/OSTEONECROSIS OF THE JAWS

2011

INTRODUZIONE I Bifosfonati (BPs), farmaci analoghi al pirofosfato, sono usati nel trattamento dell’osteoporosi, nella malattia di Paget, nel mieloma multiplo e nelle metastasi ossee. Sebbene siano molto utili nella sintomatologia osteolitica, dal 2003 è stata descritta la correlazione tra la loro somministrazione e l’insorgenza dell’osteonecrosi dei mascellari (BRONJ). Il nostro studio si propone di descrivere la superiorità delle immagini TC nei pazienti in cura con BPs affetti da BRONJ, e di raggruppare gli stessi in accordo con una classificazione radiologica basata sulla presenza o meno dei segni dell’osteomielite/osteonecrosi e delle successive complicanze. Si dimostra, inoltre, l’impo…

Current role of computed tomography-guided transthoracic needle biopsy of metastatic lung lesions.

2015

ABSTRACT  Aim: As part of the Catania symposium on lung metastasectomy we reviewed our practice of computed tomography (CT)-guided percutaneous transthoracic needle biopsy of pulmonary metastatic lesions with particular emphasis on diagnostic accuracy and nature of complications lesions. Materials & methods: 25 patients with metastatic lesions of the lung have been evaluated between May 2010 and February 2014. Inclusion criteria consisted of patients with histologically confirmed, metastatic disease of the lung, those receiving a CT-guided needle biopsy, were at least 18 years of age; and with adequate hepatic, renal and hematological function. We recorded also the size of the sampled …
