Pancreatic cancer continues to pose daily challenges clinicians, radiologists, and researchers. These are encountered at each stage of pancreatic management, including early detection, definite characterization, accurate assessment tumour burden, preoperative planning when surgical resection is possible, prediction aggressiveness, response treatment, detection recurrence. CT imaging the pancreas has made major advances in recent years through innovations research clinical practice. Technical imaging, often combination with biomarkers, hold considerable promise addressing such challenges. Ongoing dual-energy spectral photon-counting computed tomography, new applications artificial intelligence image rendering have led innovative implementations that allow now a more precise diagnosis other diseases affecting this organ. This article aims explore initiatives technological shaping landscape pancreas. By highlighting key contributions diagnostic intelligence, rendering, provides comprehensive overview how these enhancing precision improving outcome patients diseases.

Temporal bone imaging has historically suffered from spatial resolution issues because the of conventional high-resolution computed tomography (CT) is 0.5 mm, while smallest structure middle ear, stapes, very thin components, as 0.19 and small structures, such channels containing nerves arteries, have been beyond its resolution. Photon-counting ultra-high CT allow for improved reduced radiation dose compared to CT. This article provides a technical approach understanding aspects these new techniques an updated description inner well practical normal pathologic anatomy temporal in light techniques.

The temporo-mandibular joint (TMJ) links the mandibular condyle to skull, with an interposed fibrocartilaginous articular disc. TMJ disc has a nonuniform thickness that matches topographic relation between temporal bone and condyle. is stress-distributing load-absorbing structure capable of deforming adapting its shape surfaces. aim this study was analyze morphology human discs through measurements. Forty-four temporomandibular were dissected bilaterally from 22 formalin-fixed postmortem subjects. each manually measured at nine points distributed in grid formed by three zones anteroposterior direction (anterior band, intermediate band posterior band) mediolateral (medial zone, middle zone lateral zone) Microtomographic imaging analysis performed on four samples. postero-middle postero-medial significantly higher than all other points. A significant difference found bands anterior bands. also (p < 0.01) medial 0.01). Disc perforations observed 8 mostly (87.5%) located area. Micro-CT offered new possibility map variations showed very similar results those taken calipers. presented data contribute increasing knowledge specific complex 3D relations parts. They open door pioneering studies could lead clinically applicable techniques future enhance diagnosis associated osteoarthritis.

The purpose of this study was to assess the image quality and dose reduction potential ultra-high resolution (UHR) mode compared with standard mode, both available on a commercial photon-counting detector computed tomography (PCCT) scanner. Images were acquired PCCT phantom using UHR modes at three levels (3/6/12 mGy). Raw data reconstructed soft tissue (Br36) bone (Br68) reconstruction kernels 0.4-mm slice thickness. Noise power spectrum (NPS) task-based transfer function (TTF) calculated noise magnitude, texture (fav), spatial (f50), respectively. Detectability indexes (d') model detection two abdominal lesions for Br36 kernel Br68 kernel.

Preclinical and clinical diagnostics depend greatly on medical imaging, which enables the identification of physiological pathological processes in living subjects. It is often necessary to use contrast agents complement anatomical data with functional information or describe disease phenotypically. Nanomaterials are used as many advanced bioimaging techniques applications because their high payload, physicochemical properties, improved sensitivity, multimodality. Metals k-edge energy within X-ray bandwidth respond photon counting spectral imaging. This Perspective examines progress made emerging area nanoparticle-based agents. These nano
