1. High resolution tissue mass spectrometry imaging reveals a refined functional anatomy of the human adult adrenal gland. (Full text)

High resolution tissue mass spectrometry imaging reveals a refined functional anatomy of the human adult adrenal gland. In the adrenal gland, neuroendocrine cells that synthesize catecholamines and epithelial cells that produce steroid hormones are united beneath a common organ capsule to function as a single stress-responsive organ. The functional anatomy of the steroid hormone-producing adrenal cortex and the catecholamine-producing medulla is ill defined at the level of small molecules. Here (...) defined adrenal anatomy of 10 distinct molecular zones including a highly structured corticomedullary interface. By incorporating pathway information, activities of carbohydrate, amino acid, and lipid metabolism as well as endocrine bioactivity were revealed to be highly spatially organized, which could be visualized as different molecularly defined zones. Together, these findings provide a molecular definition of human adult adrenal gland structure beyond classical histological anatomy.

2. Anomalous adrenal vein anatomy complicating the evaluation of primary hyperaldosteronism (Full text)

Anomalous adrenal vein anatomy complicating the evaluation of primary hyperaldosteronism Adrenal vein development in utero occurs concurrently with the development of the inferior vena cava, the renal veins, and the gonadal veins. The embryologic formation of these veins involves communication of various venous systems. Although the left adrenal-renal vein complex is most commonly described as a shared emptying of the left adrenal vein and the left inferior phrenic vein into the left renal vein (...) , there have been reports of numerous anatomic variations of this complex. In this report, we present a case of a rare variant of the left adrenal vein, in which the left adrenal vein empties into the left gonadal vein, which takes an atypical course superolateral to the left kidney.

6. Evaluation of right adrenal vein anatomy by Dyna computed tomography in patients with primary aldosteronism (Full text)

Evaluation of right adrenal vein anatomy by Dyna computed tomography in patients with primary aldosteronism Primary aldosteronism (PA) is the most common cause of secondary hypertension and consists up to 11% of patients with hypertension. Adrenal venous sampling (AVS) is the recommended procedure for diagnosis of PA, but the technique is difficult and the right adrenal vein is especially hard to catheterize. We retrospectively examined the clinically relevant anatomy of the right adrenal vein (...) in a sample of 66 PA patients with technically successful AVS and distinctly-opacified right adrenal veins in Dyna computed tomography (CT). In the majority of cases: the right adrenal veins were catheterized when the catheter tilted posterior and rightward (57/66, 86.4%), the transverse direction of the right adrenal vein from the inferior vena cava (IVC) was posterior and rightward (55/66, 83.3%), and the vertical direction of the right adrenal vein from the IVC was caudal (52/66, 78.8%).

Quantitative angiographic anatomy of the renal arteries and adjacent aorta in the swine for preclinical studies of intravascular catheterization devices Swine are the most common animal model in preclinical studies of cardiovascular devices. Because of the recent trend for development of new devices for percutaneous catheterization, especially for the renal arteries (RAs), we examined the quantitative anatomical dimensions of the RAs and adjacent aorta in swine. Angiographic images were (...) mm, respectively; P<0.05). The branching angle of the right RA from the aorta was significantly smaller than that of the left (91 ± 12° vs. 103 ± 15°, respectively; P<0.001). The diameters of the suprarenal and infrarenal aorta were 10.6 ± 1.1 mm and 9.7 ± 0.9 mm, respectively. In conclusion, because of their similar dimensions to human, swine are an appropriate animal model for assessing the safety of, and determining optimal design of, catheter devices for RAs in simulated clinical use.

11. Role of daily plan adaptation in MR-guided stereotactic ablative radiotherapy for adrenal metastases. (Abstract)

Role of daily plan adaptation in MR-guided stereotactic ablative radiotherapy for adrenal metastases. To study interfractional organ changes during magnetic resonance (MR)-guided stereotactic ablative radiation therapy for adrenal metastases and to evaluate the dosimetric advantages of online plan adaptation.Seventeen patients underwent a total of 84 fractions of video-assisted, respiration-gated, MR-guided adaptive radiation therapy to deliver either 50 Gy (5 fractions), 60 Gy (8 fractions (...) ), or 24 Gy (3 fractions). An MR scan was repeated before each fraction, followed by rigid coregistration to the gross tumor volume (GTV) on the pretreatment MR scan. Contour deformation, planning target volume (PTV) (GTV + 3 mm) expansion, and online plan reoptimization were then performed. Reoptimized plans were compared with baseline treatment plans recalculated on the anatomy-of-the-day ("predicted plans"). Interfractional changes in organs at risk (OARs) were quantified according to OAR volume
