PET/MRI for Breast Cancer
The advent of PET/MRI, which combines metabolic PET information with high anatomical detail from MRI, has emerged as a promising tool for breast cancer diagnosis, staging, treatment response assessment, and restaging. Technical advancements including the integration of PET and MRI, considerations in patient preparation, and optimized imaging protocols contribute to the success of dedicated breast and whole-body PET/MRI.

Radiological Aspects of Sacroiliitis
Sacroiliitis is the inflammation of the sacroiliac joint, the largest axial joint in the human body, contributing to 25% of lower back pain cases. It can be detected using various imaging techniques like radiography, Magnetic Resonance Imaging (MRI), and Computed Tomography (CT) scans. Treatments range from conservative methods to invasive procedures. Recent advancements in artificial intelligence offer precise detection of this condition through imaging. Treatment options range from physical therapy and medications to invasive methods like joint injections and surgery.

Cost-Effective Diagnostic Algorithm for Intraductal Papillary Mucinous Neoplasms
The increased detection of pancreatic cysts in recent years has triggered extensive diagnostic investigations to clarify their potential risk of malignancy, resulting in a large number of patients undergoing numerous imaging follow-up studies for many years. Therefore, there is a growing need for optimization of the current surveillance protocol to reduce both healthcare costs and waiting lists, while still maintaining appropriate sensibility and specificity. Imaging is an essential tool for evaluating patients with intraductal papillary mucinous neoplasms (IPMNs) since it can assess several predictors for malignancy and thus guide further management recommendations. Although contrast-enhanced magnetic resonance imaging (MRI) with magnetic resonance cholangiopancreatography (MRCP) has been widely recommended by most international guidelines, recent results support the use of unenhanced abbreviated-MRI (A-MRI) protocols as a surveillance tool in patients with IPMN. In fact, A-MRI has shown high diagnostic performance in malignant detection, with high sensitivity and specificity as well as excellent interobserver agreement.

Monoclonal Antibodies for Targeted Fluorescence-Guided Surgery
Due to their specificity, monoclonal antibodies have significantly impacted cancer patients’ care, becoming one of the fastest-growing classes of new drugs approved for the treatment of solid tumors. Targeted fluorescence-guided surgery is a novel technology to better visualize tumor residuals intraoperatively. It consists of a fluorescent molecular probe, that, once injected, lights up the neoplastic cells during the surgical resection. In this regard, the development of an off-the-shelf large-scale production of clinically approved, fluorescently labeled monoclonal antibodies for targeted fluorescence-guided surgery is becoming an urgent need for oncological surgeons working in this field.

Radiological Diagnostic Approach and Spinal Cord Tumor
Differentiating neoplastic from non-neoplastic spinal cord pathologies may be challenging due to overlapping clinical and radiological features. Spinal cord tumors, which comprise only 2–4% of central nervous system tumors, are rarer than non-tumoral myelopathies of inflammatory, vascular, or infectious origins. The risk of neurological deterioration and the high rate of false negatives or misdiagnoses associated with spinal cord biopsies require a cautious approach.

Antibody-Based Radiopharmaceuticals Targeting Fibroblast Activation Protein
Fibroblast activation protein (FAP) is a serine protease characterized by its high expression in cancer-associated fibroblasts (CAFs) and near absence in adult normal tissues and benign lesions. This unique expression pattern positions FAP as a prospective biomarker for targeted tumor radiodiagnosis and therapy. The advent of FAP-based radiotheranostics is anticipated to revolutionize cancer management.

FLASH Radiotherapy
FLASH radiotherapy (RT) is considered one of the most promising revolutions in radiation oncology, placing itself at the intersection of technology, physics, and biology. The unique healthy tissue-sparing effect and, at the same time, the equivalent tumor response have already been identified in vivo for multiple organ systems, such as the lung, brain, skin, intestine, and blood, and even in the first human patient.

Qualitative Diagnostic Imaging for Decision Making
Recently, in the treatment of advanced esophageal cancer, evidence for combined-modality therapy has been obtained, and the usefulness of neoadjuvant therapy and conversion surgery has been reported. Neoadjuvant therapy is known to improve the results of surgery for advanced esophageal cancer. In particular, neoadjuvant chemoradiotherapy (NACRT) showed a better prognosis than chemotherapy. When a histologically effective response is obtained, the presence of a good response has been shown to significantly affect the resection rate and the long-term prognosis; thus, precise evaluation has become more important for determining the treatment strategy.

Molecularly Targeted Lanthanide Nanoparticles for Cancer Treatment
Injectable colloidal solutions of lanthanide oxides (nanoparticles between 10 and 100 nm in size) have demonstrated high biocompatibility and no toxicity when the nanoparticulate units are functionalized with specific biomolecules that molecularly target various proteins in the tumor microenvironment. Among the proteins successfully targeted by functionalized lanthanide nanoparticles are folic receptors, fibroblast activation protein (FAP), gastrin-releasing peptide receptor (GRP-R), prostate-specific membrane antigen (PSMA), and integrins associated with tumor neovasculature. Lutetium, samarium, europium, holmium, and terbium, either as lanthanide oxide nanoparticles or as nanoparticles doped with lanthanide ions, have demonstrated their theranostic potential through their ability to generate molecular images by magnetic resonance, nuclear, optical, or computed tomography imaging. Likewise, photodynamic therapy, targeted radiotherapy (neutron-activated nanoparticles), drug delivery guidance, and image-guided tumor therapy are some examples of their potential therapeutic applications.

MRI in Community-Acquired Pneumonia in the Paediatric Population
The most common acute infection and leading cause of death in children worldwide is pneumonia. Clinical and laboratory tests essentially diagnose community-acquired pneumonia (CAP). CAP can be caused by bacteria, viruses, or atypical microorganisms. Imaging is usually reserved for children who do not respond to treatment, need hospitalisation, or have hospital-acquired pneumonia. Advances in MRI protocols make it a viable alternative for diagnosing CAP and its complications.
