Meningiomas are the most frequently occurring primary tumors within the central nervous system [1], and their biological diversity results in significant differences in treatment strategies and prognosis. Ki-67, a nuclear protein, is actively expressed during cell cycle phases such as G1, S, G2, and M, representing active cell division. During these phases, Ki-67 levels gradually increase, reflecting active cell proliferation, whereas it remains absent in the quiescent G0 phase. In meningiomas, …

MR imaging with 15-channel dental coil compared with standard 20-channel coil in patients with head and neck tumours and suspected bone invasion
Head and neck tumours are the sixth most common malignant tumours worldwide and, depending on the topographical relationship, may invade adjacent structures such as the maxilla and mandible [1,2]. Oral cavity and oropharyngeal locations account for half of cases. Treatment depends on the location and size of the primary tumour, the general condition of the patient, the expected treatment-related morbidity with its functional and aesthetic consequences, and the expected success of therapy [3].

Virtual non-calcium imaging to detect bone marrow edema in patients with arthritis: a feasibility study with MRI as standard of reference
To evaluate the diagnostic performance of virtual non-calcium (VNCa) imaging derived from dual-energy CT (DECT) for the detection of bone marrow edema (BME) in patients with suspected hand arthritis using magnetic resonance imaging (MRI) as standard of reference

T1-weighted subtraction maps improve the detection of contrast-enhancing lesions in multiple sclerosis
Multiple sclerosis (MS) is a chronic autoimmune inflammatory disorder that results in axonal demyelination. It is the most common inflammatory disorder affecting the central nervous system and the leading cause of non-traumatic disability among young people in the Global North. Currently approximately 2.9 million people are diagnosed with MS worldwide, and the prevalence continues to rise.

Evaluation of the TARGET score for MRI-based detection of prostate cancer recurrence in patients treated with HIFU hemiablation
Focal therapy (FT) is an increasingly performed treatment option in selected patients with localized prostate cancer (PCa) [1]. The aim of FT is the local eradication of all known cancerous tissue, while providing less side effects than the standard procedures radical prostatectomy and radiotherapy. High-intensity focused ultrasound (HIFU) is one of the established FT modalities with the option of focal-, hemi- or whole gland ablation [2,3].

Superselective embolization of the medial calcaneal artery: a minimally invasive and novel solution for rapid pain relief in plantar fasciitis
Plantar fasciitis (PF) is the most common cause of heel pain, with a significant impact on patients’ quality of life and functional capacity. PF, which is more common in females, is usually associated with biomechanical factors [1]. Histopathological findings have shown that PF is more accurately characterized by chronic degenerative changes than by classical inflammatory processes [2]. Mechanical overload, repetitive microtrauma, and associated neovascularization are key contributors to the chr…

Timing of MRI for early treatment response prediction of chemoradiotherapy in uterine cervical cancer
Uterine cervical cancer (UCC) remains the 4th most common cancer in women worldwide, in 2020 corresponding to 6,5% of 9.2 million cancer patients, responsible for 7,7% of 4.4 million deaths [1]. UCC is the leading cause of cancer related death in 36 developing countries. In 2019, there were 568 new UCC patients in Sweden, about 1,5% of all cancer in women, and in the last decade approximately 140 deaths yearly [2].

Intramammary benign vascular proliferative lesions on MRI during neoadjuvant chemoimmunotherapy with camrelizumab in TNBC patients
Triple-negative breast cancer (TNBC), defined by the absence of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) expression, represents a heterogeneous and aggressive breast cancer (BC) subtype associated with a high recurrence risk [1]. Accounting for approximately 8 %–13 % of all breast cancers, TNBC demonstrates the poorest prognosis among molecular subtypes and has limited effective treatment options [2]. Neoadjuvant chemotherapy (NAC) i…

Voices of the future: insights from a survey on radiology training experiences and needs
Radiology residency training in Italy is structured as a comprehensive four-year program aimed at cultivating both clinical proficiency and scientific acumen among future radiologists. In Italy, radiology residency programs are regulated by University teaching regulations (Law 341/1990, art. 11), which establish the framework for professional and non-professional training. Residents are expected to acquire comprehensive knowledge of radiological diagnostic modalities and to develop competence in…

Sacroiliac CT images based deep convolutional neural network for grading patients with axial spondyloarthritis: A multi-reader multi-center study
Axial spondyloarthritis (axSpA) is a chronic inflammatory disease disorder that predominantly involves the axial skeleton, with sacroiliitis as a key diagnostic feature. The presence of radiographic sacroiliac joint (SIJ) damage is crucial in differentiating non-radiographic axSpA (nr-axSpA) from radiographic axSpA (r-axSpA) [1–4]. Sacroiliac arthritis is classified into five radiographic Grades, and achievement of Grade II and above (presence of radiologic injury) is necessary for the diagnosis…
