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…

Creación y desarrollo de un plan de control de calidad para tratamientos de radioterapia de intensidad modulada (IMRT)

2017

Dentro del proceso de control de calidad, es un hecho, la necesidad de realizar una verificación de los tratamientos de pacientes. Esto es especialmente significativo cuando se trata de tratamientos de IMRT, ya que el movimiento de las láminas se convierte en una fuente elevada de error. Esta verificación consiste en comprobar que el tratamiento que administra el acelerador coincide con el calculado en el sistema de planificación. Esta comparación, a grandes rasgos consiste en generar de un plan de tratamiento válido clínicamente un plan de verificación, administrarlo con el acelerador y mediante algún dispositivo ser capaces de recoger ese tratamiento administrado, para posteriormente comp…

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 …

Neurochemical correlates of brain atrophy in fibromyalgia syndrome: a magnetic resonance spectroscopy and cortical thickness study

2020

(1) Background: Recently, a series of clinical neuroimaging studies on fibromyalgia (FM) have shown a reduction in cortical volume and abnormally high glutamate (Glu) and glutamate + glutamine (Glx) levels in regions associated with pain modulation. However, it remains unclear whether the volumetric decreases and increased Glu levels in FM are related each other. We hypothesized that higher Glu levels are related to decreases in cortical thickness (CT) and volume in FM patients. (2) Methods: Twelve females with FM and 12 matched healthy controls participated in a session of combined 3.0 Tesla structural magnetic resonance imaging (MRI) and single-voxel MR spectroscopy focused on the thalami…
