Women often experience cervical cancer, the fourth most frequent cancer, categorized into two primary histological types, squamous cell carcinoma and adenocarcinoma. A patient's prognosis is shaped by the advancement of the disease, as well as the presence of distant growths. For effective treatment planning, precise tumor staging at the time of diagnosis is critical. Various approaches exist to classify cervical cancer, but the FIGO and TNM systems are most frequently applied. These classifications assist in patient characterization and guiding treatment. The importance of imaging in classifying patients is undeniable, with MRI playing a critical role in decisions regarding both diagnosis and treatment planning. We explore the collaborative role of MRI and standardized classification guidelines in assessing patients with cervical tumors in diverse stages within this paper.

Several applications of Computed Tomography (CT) technology's cutting-edge advancements exist within the domain of oncological imaging. Imported infectious diseases Through innovations in hardware and software, the oncological treatment protocol can be further refined. The new, formidable tubes have opened the door for low-kV acquisitions. For effective image noise management during image reconstruction, iterative reconstruction algorithms and artificial intelligence are indispensable tools. The functional information comes from spectral CT, specifically dual-energy and photon-counting CT, and perfusion CT.

Material identification, previously unachievable with single-energy CT (SECT), is enabled by the advanced technology of dual-energy CT (DECT) imaging. The post-processing study's use of virtual monochromatic images and virtual non-contrast (VNC) images reduces radiation exposure, as it avoids the need for the preliminary pre-contrast scan. Virtual monochromatic imagery demonstrates increased iodine contrast with decreased energy levels, yielding improved visualization of hypervascular lesions and superior tissue contrast between hypovascular lesions and the surrounding parenchyma. This subsequently enables a reduction in iodinated contrast material, especially advantageous for patients with compromised kidney function. For oncology applications, these benefits hold particular significance, permitting the overcoming of many SECT imaging constraints and fostering safer and more accessible CT procedures for vulnerable patients. Within the scope of this review, the theoretical framework of DECT imaging and its use in standard oncologic clinical practice is analysed, with a concentration on the advantages it provides for patients and radiologists.

Interstitial cells of Cajal within the gastrointestinal system are the origin of gastrointestinal stromal tumors (GISTs), which are the most prevalent intestinal neoplasms. Generally, gastrointestinal stromal tumors (GISTs) often exhibit no noticeable symptoms, particularly in their early stages or when the tumors are small, which frequently leads to their discovery during routine abdominal computed tomography (CT) scans. The introduction of receptor tyrosine kinase inhibitors has had a profound impact on the efficacy of treatment for high-risk gastrointestinal stromal tumors (GISTs). Imaging's contribution to diagnosis, characterization, and ongoing monitoring will be the subject of this paper. Our local radiomic evaluation of GISTs will also be reported.

Neuroimaging techniques are crucial for diagnosing and distinguishing brain metastases (BM) in individuals with confirmed or suspected malignancies. Computed tomography and magnetic resonance imaging are the critical imaging procedures for the discovery of bone marrow (BM). click here Advanced imaging techniques, encompassing proton magnetic resonance spectroscopy, magnetic resonance perfusion, diffusion-weighted imaging, and diffusion tensor imaging, can contribute significantly to accurate diagnosis, especially in cases of newly diagnosed solitary enhancing brain lesions in patients without a history of cancer. In addition to other applications, imaging is performed to anticipate and/or gauge the efficacy of treatment, and to differentiate residual or recurrent tumors from issues originating from therapy. Beyond that, the current rise of artificial intelligence is facilitating a broad spectrum for scrutinizing numerical information derived from neuroimaging. Employing numerous images, this review provides a current summary of imaging techniques in BM patients. CT, MRI, and PET scans showcase typical and atypical imaging features of parenchymal and extra-axial brain masses (BM), highlighting advanced imaging's problem-solving role in patient management.

Currently, the treatment of renal tumors with minimally invasive ablative techniques is more frequently employed and readily achievable. The integration of new imaging technologies has effectively improved tumor ablation guidance. This review investigates the use of real-time multi-modal imaging, robotic and electromagnetic navigation systems, and artificial intelligence software in the context of renal tumor ablation.

The most frequent liver malignancy, hepatocellular carcinoma (HCC), is a significant contributor to the top two causes of cancer mortality. A cirrhotic liver is a predisposing factor for the development of hepatocellular carcinoma (HCC) in roughly 70-90% of cases. According to the latest guidelines, the imaging patterns of HCC displayed on contrast-enhanced CT or MRI are frequently sufficient for an accurate diagnosis. Contrast-enhanced ultrasound, CT perfusion, dynamic contrast-enhanced MRI, diffusion-weighted imaging, and radiomics are among the novel imaging techniques recently employed, thus leading to enhanced diagnostic accuracy and characterization of hepatocellular carcinoma (HCC). This assessment of HCC showcases the leading-edge non-invasive imaging methods and their recent developments.

The escalating use of medical cross-sectional imaging techniques has resulted in a higher incidence of incidentally discovered urothelial cancers. To discern clinically significant tumors from benign conditions, improved lesion characterization is currently required. Osteoarticular infection Cystoscopy constitutes the gold standard for bladder cancer diagnosis, whereas computed tomographic urography and flexible ureteroscopy are preferred for upper tract urothelial cancer. Using a protocol that combines pre-contrast and post-contrast imaging, computed tomography (CT) forms the cornerstone for evaluating both locoregional and distant disease. During the urography phase of the acquisition protocol for urothelial tumors, renal pelvis, ureter, and bladder lesions can be assessed. Repeated exposure to ionizing radiation and multiple doses of iodinated contrast agents are frequent in multiphasic CT scans, potentially posing risks, particularly for patients with allergies, kidney problems, pregnancies, and children. Dual-energy CT circumvents these challenges with several techniques, one of which is the generation of virtual noncontrast images from a single-phase contrast-enhanced scan. Using recent literature, we delve into the role of Dual-energy CT in the diagnosis of urothelial cancer, its potential in this clinical setting, and its related advantages.

Primary central nervous system lymphoma (PCNSL), a rare extranodal non-Hodgkin's lymphoma, accounts for a percentage between 1% and 5% of central nervous system tumors. Contrast-enhanced magnetic resonance imaging is the most suitable method for imaging. PCNLs frequently target the periventricular and superficial regions, often in close proximity to ventricular or meningeal structures. Despite the possibility of distinctive imaging findings in PCNLs on standard MRI scans, these features do not uniquely identify them and distinguish them from other brain lesions. CNS lymphoma often demonstrates characteristic imaging findings: diffusion restriction, reduced perfusion, increased choline/creatinine ratios, decreased N-acetyl aspartate (NAA) signals, along with lactate and lipid peaks. This assists in differentiating primary central nervous system lymphomas (PCNSLs) from other brain tumors. In addition, innovative imaging techniques will likely become essential in the creation of new targeted therapeutic approaches, in determining prognosis, and in overseeing the response to treatment in the foreseeable future.

To appropriately manage patients, the assessment of tumor response after neoadjuvant radiochemotherapy (n-CRT) enables patient stratification. The histopathological examination of the surgical specimen continues to be considered the gold standard in assessing tumor response; nevertheless, the advancements in magnetic resonance imaging (MRI) have led to improved accuracy in evaluating the effectiveness of treatment The tumor regression grade, as observed radiologically (mrTRG) using MRI, is comparable to the pathologically assessed tumor regression grade (pTRG). Predicting the effectiveness of therapy in its early stages can be enhanced with additional data from functional MRI parameters. Functional methodologies, including diffusion-weighted MRI (DW-MRI) and perfusion imaging (dynamic contrast enhanced MRI [DCE-MRI]), are already integrated into clinical practice.
