Article Synopsis
  • The study investigated the significance of metabolic tumor volume (tMTV) in patients with advanced non-small cell lung cancer (NSCLC) undergoing immune checkpoint blockade (ICB) therapy, using 18F-FDG-PET/CT scans.
  • It involved 518 patients across multiple institutions and found that those with high tMTV had poorer overall survival when treated with ICBs alone compared to those with low tMTV.
  • The research suggests that high tMTV is associated with increased systemic inflammation and genomic instability, making it a potential biomarker for determining treatment strategies in NSCLC patients with positive PD-L1 expression.

Article Synopsis
  • The study focuses on identifying effective treatment responses in patients with metastatic castration-resistant prostate cancer (mCRPC) using positron emission tomography (PET) with different radiotracers.
  • A total of 49 patients were randomly assigned to receive scans using C-Choline, F-FACBC, or Ga-PSMA before treatment and again 2 months later to evaluate their biochemical response, primarily looking for a PSA reduction of ≥50%.
  • Results indicated that variations in metabolic tumor volume (MTV) and total lesion activity (TLA) with Ga-PSMA PET were significantly associated with treatment responses and could also predict progression-free survival and overall survival in patients.

: Cardiac magnetic resonance (CMR) imaging has become an essential instrument in the study of cardiomyopathies; it has recently been integrated into the diagnostic workflow for cardiac amyloidosis (CA) with remarkable results. An additional emerging role is the stratification of the arrhythmogenic risk by scar analysis and the possibility of merging these data with electro-anatomical maps. This is made possible by using a software (ADAS 3D, Galgo Medical, Barcelona, Spain) able to provide 3D heart models by detecting fibrosis along the whole thickness of the myocardial walls.

The application of cardiac magnetic resonance (CMR) imaging in clinical practice has grown due to technological advancements and expanded clinical indications, highlighting its superior capabilities when compared to echocardiography for the assessment of myocardial tissue. Similarly, the utilization of implantable cardiac electronic devices (CIEDs) has significantly increased in cardiac arrhythmia management, and the requirements of CMR examinations in patients with CIEDs has become more common. However, this type of exam often presents challenges due to safety concerns and image 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.

The ultra-high frequency ultrasound (UHFUS) is characterized by the use of probes between 30 and 100 MHz. This technology has recently been introduced in clinical practice and represents an opportunity for the diagnosis of numerous pathologies. The high spatial resolution of UHFUS, up to 30 μ in pixel size, allows to study the pathological modifications and to guide microsurgery treatments in anatomical body structures not evaluable by conventional HFUS.

Introduction: Paraneoplastic pemphigus (PNP) is an autoimmune disorder that is almost always linked to an underlying neoplasia. General radiologists are usually not aware of what kind of neoplasia can be associated with PNP. Therefore, this study evaluates the effect of a dermatology lecture on radiologists' neoplasia diagnosis performance.

Neuroendocrine neoplasms (NEN) are a heterogeneous group of tumours derived from cells of neuroendocrine origin and can potentially arise everywhere in the human body. The diagnostic assessment of NEN can be performed using a variety of PET radiopharmaceuticals. Well-differentiated NEN (NET) present a high expression of SSTR (somatostatin receptors) and can therefore be studied with 68Ga-DOTA-peptides ([68Ga]Ga-DOTANOC, [68Ga]Ga-DOTATOC, [68Ga]Ga-DOTATATE).

Neuroendocrine neoplasms (NENs) are rare and heterogeneous tumors that require multidisciplinary discussion for optimal care. The theranostic approach (DOTA peptides labelled with Ga for diagnosis and with Y or Lu for therapy) plays a crucial role in the management of NENs to assess disease extension and as a criteria for peptide receptor radionuclide therapy (PRRT) eligibility based on somatostatin receptor (SSTR) expression. On the diagnostic side, [Ga]Ga-DOTA peptides PET/CT (SSTR PET/CT) is the gold standard for imaging well-differentiated SSTR-expressing neuroendocrine tumors (NETs).

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths worldwide and one of the most common causes of death among patients with cirrhosis, developing in 1-8% of them every year, regardless of their cirrhotic stage. The radiological features of HCC are almost always sufficient for reaching the diagnosis; thus, histological confirmation is rarely needed. However, the study of cirrhotic livers remains a challenge for radiologists due to the developing of fibrous and regenerative tissue that cause the distortion of normal liver parenchyma, changing the typical appearances of benign lesions and pseudolesions, which therefore may be misinterpreted as malignancies.
