Ultrasound-guided preoperative localization of breast lesions: a good choice.

Purpose: The aim of the study was to verify whether ultrasound (US)-guided preoperative localization of breast lesions is an adequate technique for correct and safe surgical resection and to contribute positively and effectively to this topic in the literature with our results.

Methods: From June 2016 to November 2016, 155 patients with both benign and malignant breast lesions were selected from our institute to undergo US localization before surgery. The lesions included were: sonographically visible and nonpalpable lesions; palpable lesions for which a surgeon had requested US localization to better evaluate the site and extension; sonographically visible, multifocal breast lesions, both palpable and nonpalpable.

Magnetic resonance imaging appearance of oxidized regenerated cellulose in breast cancer surgery.

Purpose: To describe magnetic resonance imaging (MRI) findings in patients who underwent breast-conserving surgery followed by oxidized regenerated cellulose (ORC) implantation in surgical cavity.

Materials And Methods: We retrospectively reviewed 51 MRI examinations performed between January 2009 and January 2014 in 51 patients who underwent BCS with ORC implantation.

Results: In 29/51 (57 %) cases, MRIs showed abnormal findings with three main MRI patterns: (1) complex masses: hyperintense collections on T2-weighted (w) images with internal round hypointense nodules without contrast enhancement (55 %); (2) completely hyperintense collections (17 %); and (3) completely hypointense lesions (28 %).

Comparison between whole-body MRI and Fluorine-18-Fluorodeoxyglucose PET or PET/CT in oncology: a systematic review.

Background: The aim of the article is to systematically review published data about the comparison between positron emission tomography (PET) or PET/computed tomography (PET/CT) using Fluorine-18-Fluorodeoxyglucose (FDG) and whole-body magnetic resonance imaging (WB-MRI) in patients with different tumours.

Methods: A comprehensive literature search of studies published in PubMed/MEDLINE, Scopus and Embase databases through April 2012 and regarding the comparison between FDG-PET or PET/CT and WB-MRI in patients with various tumours was carried out.

Results: Forty-four articles comprising 2287 patients were retrieved in full-text version, included and discussed in this systematic review.

Usefulness of hybrid SPECT/CT for the 99mTc-HMPAO-labeled leukocyte scintigraphy in a case of cranial osteomyelitis.

Cranial osteomyelitis is a potentially fatal lesion. White blood cell scanning (WBC) with 99mTc-hexamethylpropylene amine oxime (HMPAO) has proven highly sensitive and specific in the diagnosis and follow-up of patients with suspected osteomyelitis. In this report we show the usefulness of SPECT and transmission CT performed simultaneously using a hybrid imaging device for the functional anatomic mapping of soft tissue and cranial bone infections.

Molecular imaging of atheroslerotic plaque with nuclear medicine techniques.

Atherosclerosis is a systemic disease of the vessel wall that mainly affects medium- and large-sized arteries, and accounts for 50% of all deaths in western countries. Imaging of atheromatous plaques has traditionally centered on assessing the degree of luminal narrowing. More recently it has become clear that it is of the utmost importance to identify the vulnerable atherosclerotic plaques responsible for the majority of life-threatening syndromes.
