“…After clarifying the 3D CCS arrangement in humans, research of 4D CCS changes is expected to accelerate with advanced technological progress 48 . 4D CCS changes related to the time axis, such as developmental 23 , 49 – 51 , growth and aging 44 , 45 , and normal versus pathologic 52 , 53 , can enhance our understanding.…”

Current advanced imaging modalities with applied tracing and processing techniques provide excellent visualization of almost all human internal structures in situ; however, the actual 3D internal arrangement of the human cardiac conduction system (CCS) is still unknown. This study is the first to document the successful 3D visualization of the CCS from the sinus node to the bundle branches within the human body, based on our specialized physical micro-dissection and its CT imaging. The 3D CCS transformation by cardiac inclination changes from the standing to the lying position is also provided. Both actual dissection and its CT image-based simulation identified that when the cardiac inclination changed from standing to lying, the sinus node shifted from the dorso-superior to the right outer position and the atrioventricular conduction axis changed from a vertical to a leftward horizontal position. In situ localization of the human CCS provides accurate anatomical localization with morphometric data, and it indicates the useful correlation between heart inclination and CCS rotation axes for predicting the variable and invisible human CCS in the living body. Advances in future imaging modalities and methodology are essential for further accurate in situ 3D CCS visualization.

“…Post-processing is required to visualise and interpret SHR-CTA datasets and to communicate findings to referring physicians [8,9,22,23]. Post-processing includes multiplanar reconstruction (MPR), maximum intensity projection (MIP) images, and volume rendering technique (VRT), which has been replaced by global illumination rendering (GI) [24,25].…”

Vascular lesions of the hand are common and are distinct from vascular lesions elsewhere because of the terminal vascular network in this region, the frequent hand exposure to trauma and microtrauma, and the superficial location of the lesions. Vascular lesions in the hand may be secondary to local pathology, a proximal source of emboli, or systemic diseases with vascular compromise. In most cases, ischaemic conditions are investigated with Doppler ultrasonography. However, computed tomography angiography (CTA) or dynamic contrast-enhanced magnetic resonance angiography (MRA) is often necessary for treatment planning. MR imaging is frequently performed with MRA to distinguish between vascular malformations, vascular tumours, and perivascular tumours. Some vascular tumours preferentially affect the hand, such as pyogenic granulomas or spindle cell haemangiomas associated with Maffucci syndrome. Glomus tumours are the most frequent perivascular tumours of the hand. The purpose of this article is to describe the state-of-the-art acquisition protocols and illustrate the different patterns of vascular lesions and perivascular tumours of the hand.

“…New CT scanners offer a slice thickness of 0.25 mm, very small focal spots, and better data sampling that greatly improve image quality. 47 Multiplanar reconstruction is very useful to evaluate the displacement and the angulation of the bone fragments. Special attention must be paid to thumb positioning.…”

“…Global illumination rendering (also known as cinematic rendering) improves the image quality compared with routine volume rendering techniques. [47][48][49] Four-dimensional CT achievable with devices with large detection system could play a role in the analysis of normal and pathologic kinematics of different joints. [50][51][52][53] CT angiography can be useful to evaluate vascular lesions and rule out a tumor 54,55 (►Fig.…”

The unique anatomical characteristics of the thumb offer a broad range of motion and the ability to oppose thumb and finger, an essential function for grasping. The motor function of the thumb and its orientation make it particularly vulnerable to trauma. Pathologic lesions encountered in this joint are varied, and imaging techniques play a crucial role in injury detection and characterization. Despite advances in diagnostic accuracy, acute thumb injuries pose a challenge for the radiologist. The complex and delicate anatomy requires meticulous and technically flawless image acquisition. Standard radiography and ultrasonography are currently the most frequently used imaging techniques. Computed tomography is most often indicated for complex fractures and dislocations, and magnetic resonance imaging may be useful in equivocal cases. In this article, we present the relevant anatomy and imaging techniques of the thumb.
