Multimodality imaging features of small bowel cancers complicating Crohn's disease: a pictorial review.

Patients with Crohn's disease (CD) are at increased risk of developing small bowel cancer, since chronic inflammation may trigger the histopathological sequence that begins from low-grade dysplasia of the intestinal epithelium and may eventually lead to malignant transformation. Owing to their location in a portion of the gastrointestinal tract which is not easily accessible to conventional endoscopic techniques, the detection of CD-related small bowel cancers is still a clinical challenge. The radiological features of CD-related small bowel adenocarcinoma (SBA) in patients with CD have been described in some previous studies, including its appearance in both CT and MRI examinations.

To Enhance or Not to Enhance? The Role of Contrast Medium F-FDG PET/CT in Recurrent Ovarian Carcinomas.

: F-fluorodeoxyglucose (FDG) positron emission tomography/X-ray computed tomography (PET/CT) represents the mainstay diagnostic procedure for suspected ovarian cancer (OC) recurrence. PET/CT can be integrated with contrast medium and in various diagnostic settings; however, the effective benefit of this procedure is still debated. We aimed to compare the diagnostic capabilities of low-dose and contrast-enhanced PET/CT (PET/ldCT and PET/ceCT) in patients with suspected ovarian cancer relapse.

Clinical and FDG-PET/CT correlates in patients with polymyalgia rheumatica.

Objectives: We aimed to evaluate joint and vessel uptake in patients with polymyalgia rheumatica (PMR) by FDG-PET and correlate it with clinical findings.

Methods: Consecutive PMR patients, without clinical signs of giant cell arteritis, underwent a standardised clinical examination and FDG-PET/CT. Controls were consecutive subjects undergoing FDG-PET for the suspicion of neoplasm not confirmed by the examination.

A rare case of maxillary nodular fasciitis: Case report and short literature review.

Nodular fasciitis has to be considered as an option in the presence of a solitary, rapidly growing mass even in older adults. When possible, direct surgery should be preferred to FNAC, particularly in the older adults because of high misdiagnostic risk.

Contamination inside CT gantry in the SARS-CoV-2 era.

We investigated whether the internal gantry components of our computed tomography (CT) scanner contain severe acute respiratory syndrome 2 (SARS-CoV-2) ribonucleic acid (RNA), bacterial or fungal agents. From 1 to 27 March 2020, we performed 180 examinations of patients with confirmed SARS-CoV-2 infection using a dedicated CT scanner. On 27 March 2020, this CT gantry was opened and sampled in each of the following components: (a) gantry case; (b) inward airflow filter; (c) gantry motor; (d) x-ray tube; (e) outflow fan; (f) fan grid; (g) detectors; and (h) x-ray tube filter.

Copper, PET/CT and prostate cancer: a systematic review of the literature.

Copper is an essential element that plays an important role in both cancer development and growth. Indeed, high levels of copper have been found in prostate cancer (PCa), and this finding have paved the way for the use of this element as a target for positron emission tomography (PET) imaging. Copper64 (64Cu) can be used alone, as CuCl2, and also as a precursor for the in-vitro radio-labelling of specific carriers for PET imaging in PCa, (e.

Diagnostic value of retrospectively fused CuCl PET/MRI in biochemical relapse of prostate cancer: comparison with fused F-Choline PET/MRI, CuCl2 PET/CT, F-Choline PET/CT, and mpMRI.

Purpose: To assess the diagnostic value of retrospectively fused PET/MRI by comparing the detection rates (DRs) of fused CuCl PET/MRI vs. fused F-Choline PET/MRI in patients with suspected prostatic cancer (PCa) recurrence. The secondary objective was to compare the DRs of fused PET/MRI vs.

Solitary Fibrous Tumor of the Prostate.

Even though most tumors located in the prostate derive from prostatic glands, there is a long list of malignant and nonmalignant causes for prostatic growths that clinicians should be aware of. Tumors of the prostate can be grouped in epithelial, neuroendocrine, stromal, mesenchymal, hematolymphoid, and miscellaneous. Solitary fibrous tumor of the prostate (SFT), is an extremely rare mesenchymal tumor (only about 20 cases reported in the literature).

An Exploratory Study of Adult Baby-Diaper Lovers' Characteristics in an Italian Online Sample.

Background: Knowledge of the Adult Baby-Diaper Lovers (ABDL) phenomena is quite recent and there are, of yet, few studies on this phenomenon.

Aim: This study was conceived to investigate the functions of ABDL behaviours and the characteristics of ABDL in an online Italian community sample. We hypothesized that ABDL phenomena were associated with general psychological maladjustment and with an experience of parental rejection during childhood.

Noninvasive liver fibrosis assessment in chronic viral hepatitis C: agreement among 1D transient elastography, 2D shear wave elastography, and magnetic resonance elastography.

Purpose: To assess the agreement of one-dimensional transient elastography (1D-TE), two-dimensional shear wave elastography (2D-SWE), and magnetic resonance elastography (MRE) in a consecutive cohort of patients affected by hepatitis C virus (HCV) and to understand which patient-related factors are associated with disagreement.

Methods: Ninety-one consecutive patients with current or previous chronic HCV infection were enrolled between March 2017 and September 2018. We assessed the correlation between stiffness measurements expressed in kilopascals (kPa).

We prospectively evaluated 50 PCa patients with biochemical relapse after surgery or external-beam radiation therapy. All patients underwent CuCl PET/CT, F-choline PET/CT, and multiparametric MRI within 15 d of each other.

A rare case of parotid gland lipoma arising from the deep lobe of the parotid gland.

Lipomas are the most commonly encountered benign mesenchymal tumors, but their occurrence in the head and neck is rare, even more at the level of the parotid region where they can be found nearby the parotid capsule, inside the capsule, or within the gland. In addition, lipomas involving the deep parotid lobe are extremely unusual. That is why lipomas are not often considered for differential diagnosis of parotid lumps.

Renal trauma in adolescent skateboarders.

Objective: Kidney is the most commonly injured organ of the genitourinary tract after trauma. Half of blunt renal injuries are caused by traffic accidents, but sport activities are also included as frequent causes. Skatebording is popular among young people but it deserves being considered a potential cause of severe injuries.

Magnetic resonance imaging of breast cancer: does the time interval between biopsy and MRI influence MRI-pathology discordance in lesion sizing?

Background Breast magnetic resonance imaging (MRI) is more accurate than ultrasound and mammography in estimating local extension of both invasive breast cancer and ductal carcinoma in situ (DCIS) and it is part of a breast cancer patient's preoperative management. Purpose To verify if time interval between breast biopsy and preoperative MRI, lesion margins, and biopsy technique can influence tumor sizing on MRI. Material and Methods By a database search, we retrospectively identified all women with a newly diagnosed, biopsy-proven, primary breast cancer who underwent MRI before surgery.

Lung hyperaeration assessment by computed tomography: correction of reconstruction-induced bias.
