Although contrast-enhanced ultrasound (CEUS) is a widespread and easily manageable technique, image interpretation errors can occur due to the operator's inexperience and/or lack of knowledge of the frequent pitfalls, which may cause uncertain diagnosis and misdiagnosis. Indeed, knowledge of the basic physical and technical principles of ultrasound is needed both to understand sonographic image findings and to evaluate the potential and limits of the method. Like the B-mode ultrasound, the quality of the CEUS examination is also subject not only to the adequate manual skill of the operator but also to his/her deep knowledge of the technique which improves the quality of the image helping avoid misleading artifacts.

A cardiac lesion detected at ultrasonography might turn out to be a normal structure, a benign tumor or rarely a malignancy, and lesion characterization is very important to appropriately manage the lesion itself. The exact relationship of the mass with coronary arteries and the knowledge of possible concomitant coronary artery disease are necessary preoperative information. Moreover, the increasingly performed coronary CT angiography to evaluate non-invasively coronary artery disease leads to a rising number of incidental findings.

Cognitive impairment is one of the most prevalent symptoms of post Severe Acute Respiratory Syndrome COronaVirus 2 (SARS-CoV-2) state, which is known as Long COVID. Advanced neuroimaging techniques may contribute to a better understanding of the pathophysiological brain changes and the underlying mechanisms in post-COVID-19 subjects. We aimed at investigating regional cerebral perfusion alterations in post-COVID-19 subjects who reported a subjective cognitive impairment after a mild SARS-CoV-2 infection, using a non-invasive Arterial Spin Labeling (ASL) MRI technique and analysis.

Background: Lung cancer represents a heterogeneous group of neoplasms, with the highest frequency and mortality in both sexes combined. In a clinical scenario characterized by the widespread of multidetector-row spiral CT, core-needle biopsy under tomographic guidance is one of the main and safest methods to obtain tissue specimens, even though there are relatively high rates of pneumothorax (0-60% incidence) and pulmonary hemorrhage (4-27% occurrence rates). The aim of this retrospective study is to assess the diagnostic accuracy of CT-guided core-needle biopsy in the diagnosis of primary lung malignancies and to compare our results with evidence from the literature.

Introduction: The placement of vascular catheters of adequate size in accordance to catheter-to-vein ratio (CVR) recommendations represents one of the cornerstones of catheter-related upper vein thrombosis prevention. However there is scarcity of data on its effect on the venous dynamics of the basilic vein, a common site for long-term catheter placement. This study investigates the effects of the application of positive airway pressure on the diameter and blood flow velocity of basilic vein.

With the regional law n. 26 of December 30, 2020, the Friuli Venezia Giulia Region wanted to promote the establishment of the Regional Register of Sudden Cardiac Death, with the aim of favoring the study of all those deaths that occurred suddenly and unexpectedly under the age of 50 years in which it is not possible to trace the cause of death with certainty. Such dramatic events, difficult to quantify considering the complexity of data collection, are often accepted with resignation without any further investigation of the possible causes.

Context: Unlike palpable lumps, a large number of nonpalpable testicular lesions found incidentally at ultrasound in asymptomatic postpuberal males are either benign tumours or non-neoplastic lesions. The prevalence of malignancy, however, is appraised based on small case series. Dedicated studies report a large number of patients, and systematic review articles are lacking.

Article Synopsis
  • The study evaluates the effectiveness and safety of Percutaneous Cryoablation (PCA) for small renal masses (SRMs) in patients unsuitable for surgery, analyzing data from four centers over a 10-year period.
  • Patients were categorized based on the size of their masses into two groups, with results indicating a significantly higher success rate (Trifecta outcomes) in smaller masses compared to larger ones, and a notable increase in complications for the larger group.
  • Overall, PCA shows promise as a safe and effective treatment, but suggests that stricter size limits may improve success rates for managing SRMs.

Apicomplexan parasites secrete contents of the rhoptries, club-shaped organelles in the apical region, into host cells to permit their invasion and establishment of infection. The rhoptry secretory apparatus (RSA), which is critical for rhoptry secretion, was recently discovered in Toxoplasma and Cryptosporidium. It is unknown whether a similar molecular machinery exists in the malaria parasite Plasmodium.

Apicomplexa are obligatory intracellular parasites that sense and actively invade host cells. Invasion is a conserved process that relies on the timely and spatially controlled exocytosis of unique specialized secretory organelles termed micronemes and rhoptries. Microneme exocytosis starts first and likely controls the intricate mechanism of rhoptry secretion.

Objective Among the clinical manifestations of stroke mimics, isolated aphasia is one of the most challenging due to its aetiopathogenic diagnosis. This short communication describes a specific perfusion and brain oscillatory pattern in a challenging case of prolonged isolated aphasia caused by status epilepticus, jointly investigated by computed tomography (CT) perfusion, single-photon emission computerized tomography (SPECT)/CT and EEG qualitative and quantitative analysis. Methods We discuss the different patterns of perfusion neuroimaging and EEG between SE and ischaemic stroke or postictal (Todd's)-related isolated aphasia, and propose these differences as a basis to support the differential diagnosis.

  • Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare but serious condition that can develop after an acute pulmonary embolism, leading to high morbidity and mortality due to its impact on right ventricular function.
  • The preferred treatment for operable patients is pulmonary endarterectomy (PEA), which significantly improves symptoms and prognosis by reducing pulmonary vascular resistance.
  • Not all CTEPH patients qualify for PEA due to factors like distal vascular obstruction or other health issues, so thorough evaluation by a specialized team is crucial for treatment selection.

Article Synopsis
  • The study focused on using high-resolution CT scans to identify characteristics of COVID-19-associated pulmonary aspergillosis (CAPA), particularly looking for new or worsening bronchiectasis in patients.
  • Researchers analyzed data from 350 mechanically ventilated ICU patients, finding a significant incidence of bronchiectasis (57.9%) among those with CAPA, most of whom were elderly males.
  • The findings suggest that radiologic signs of bronchiectasis in COVID-19 patients warrant further investigation for potential fungal infections, as the mortality rate for those with CAPA was greater than 60% after six months.

Imaging plays a pivotal role in systemic sclerosis for both diagnosis management of pulmonary complications, and high-resolution computed tomography (HRCT) is the most sensitive technique for the evaluation of systemic sclerosis-associated interstitial lung disease (SSc-ILD). Indeed, several studies have demonstrated that HRCT helps radiologists and clinicians to make a correct diagnosis on the basis of recognised typical patterns for SSc-ILD. Most SSc patients affected by ILD have a non-specific interstitial pneumonia pattern (NISP) on HRCT scan, whilst a minority of cases fulfil the criteria for usual interstitial pneumonia (UIP).
