“…Nevertheless, the enlargement seen in the present data corresponds to the lower end of enlargement reported in anatomical dissections. 3 Other studies show greater enlargement, 6 whereas others were not directly comparable, as they reported CB size in terms of weight or volume. 2,5,7,9,10 As a retrospective study, these clinical CTAs were not intended to evaluate the CB, so visualization quality ranged from optimal to poor.…”

“…7 The degree of enlargement has been described as ranging from 20% to 130% compared to non-afflicted control samples. 3,6 Despite the anatomical pathology literature, in situ CB morphology has not been previously linked to disease states in humans. The first study to characterize the normal CB using CTA was published in 2011.…”

In the late 20 th century, it was found that the basic function of the CB is chemical control of the regulation of respiratory action by means of a reflex from chemoreceptors, but it was not until the last 15 years that research has revealed another important function: the chemoreceptors present in the CB play an essential role in regulating the functions of the circulatory system [3][4][5]. Research connected with the carotid body is currently focused on establishing the significance of chronically increased CB activity in the progression of heart failure and in the genesis of hypertension [6][7][8][9]. Patients with heart failure display (for example)The carotid body (CB) is an anatomically minor structure located on both sides of the bifurcation of the external and internal carotid artery, slightly towards the back. It does not normally exceed the dimensions of 7 × 4 × 2 mm [1].Recently, the clinical significance of the carotid body has been increasing. A group of tumors known as paragangliomas originates from the carotid body, and it has recently been suggested that a CB diameter exceeding 6 mm may be related to a heightened risk of developing paragangliomas, especially in persons with a known family occurrence AbstractBackground. The clinical significance of the carotid body (CB) has been increasing. Currently, research connected with the CB is focused on establishing the significance of chronically increased activity of the CB in the progression of heart failure and in the genesis of hypertension. Moreover, it has been suggested that cardiac hypertrophy may be associated with an increase in CB volume.Objectives. The aim of study was to assess the quality of imaging the CB by following the standard protocol for computed tomography angiography (CTA) of the carotid arteries. Material and Methods. The analysis includes 50 consecutive CTA examinations of the carotid arteries. A retrospective assessment of the quality of imaging both the right and left CB (rCB and lCB) was carried out for all the CTA examinations of the carotid arteries. Results. The rCB was exposed in 62% and the lCB in 56% of the CTA examinations. None of the CTA examinations analyzed resulted in good or very good quality visualization of the CB. Only 22% of the CTA examinations provided a medium quality rCB image. An even lower ratio of medium-quality visualizations of the lCB was noted: only 14% of the analyzed examinations. In the male sample group, the CB was exposed significantly more often than in the female group. Conclusions. The standard protocol for CTA examinations of the carotid arteries appears to be insufficient for use in assessing the CB (Adv Clin Exp Med 2015, 24, 6, 1037-1043).
