This study introduces an anatomical basis for surgeries such as thoracoscopeassisted thoracolumbar spinal anterior interbody fusion in terms of image observing and corpse specimen anatomising. The observation of the 3-dimensional computed tomography (CT) image indicates that segmental arteries are visible and run in the central supersulcus of the corresponding vertebral body’s side, while the branches are invisible. The distances between adjacent segmental arteries in T₁₀/₁₁, T₁₁/₁₂, T₁₂ /L₁, L₁/₂,, and L₂/₃ are 23.35 ± 1.48, 25.61 ± 2.08, 29.12 ± 2.30, 32.53 ± 2.18, and 33.73 ± 2.29 (mm), respectively. And the observation by the thoracolumbar spine side of the adult corpse specimens shows that segmental arteries and veins constantly exist and run in the central supersulcus of the corresponding vertebral body’s side; each segmental artery has some small branches; the zone between the upper and lower segmental arteries form a relatively non-vascular nerve safe zone, where the intervertebral space (disc) locates. The distances between adjacent segmental arteries in T₁₀/₁₁, T₁₁/₁₂, T₁₂ /L₁,L₁/₂,L₂/₃ are 23.34 ± 0.78, 25.54 ± 0.85, 29.11 ± 1.01, 32.82 ± 1.28, and 33.71 ± 1.42 (mm), respectively. The safe zone, with the intervertebral disc as the reference mark, can provide enough operation space for surgeries like thoracoscope-assisted anterior interbody fusion and reducing damage to blood vessels as well as surgical complications. Additionally, the arrangement and distribution of segmental arteries can be clearly displayed on the 3-dimensional CT image and the result is basically consistent with that of corpse specimens. Therefore, the 3-dimensional CT image can be regarded as the reference for video-assisted thoracoscopic surgery plans. (Folia Morphol 2010; 69, 3: 128–133)
An autopsy or necropsy can be performed only once; therefore, its proper execution is of fundamental importance in explaining the cause of death. The protocol with photographic documentation is an integral part of the autopsy, but sometimes it does not fully reflect the state of the body and the pathological changes observed at each stage of the procedure. These shortcomings are addressed by modern imaging techniques, which are increasingly used during the autopsy of human bodies, but quite rarely during necropsy of animals. Non-invasive techniques (CT, MRI, or photogrammetry with laser body scanning), or in some cases also minimally invasive techniques (biopsy), enable comprehensive analysis of the carcass, but Virtopsy is only a supplement to the classical autopsy, especially in veterinary forensic medicine.
Ultrasonography is a noninvasive diagnostic tool used to image size, shape, parenchyma and vascularization of various body organs. Unfortunately, the ultrasonographic image is characterized by a low contrast due to similar acoustic properties of the soft tissue. The Doppler mode provides information about blood flow, but is incapable of imaging small vessels and capillaries because of their low blood flow velocity (1 mm/s). However, a possibility to increase the effectiveness of ultrasonographic diagnostics exists, thanks to intravenous ultrasound contrast agents (UCAs) consisted of gas microbubbles. The purpose of this review paper is to characterize specific imaging techniques necessary to conduct a contrast-enhanced liver examination and indications for CEUS as an alternative diagnostic method.
The objective of the present research was to assess the usability of three diagnostic imaging modalities for canine prostate gland evaluation. The studies included 33 male dogs of various breeds. A radiographic diagnostic procedure was employed as well as dual modality ultrasound imaging, i.e. transabdominal (TAUS) and transrectal (TRUS). Radiograms were studied to evaluate the prostate gland size and localisation. Both ultrasound imaging techniques were compared regarding the imaging of various prostate parenchyma areas. It was found that a suitable USG modality should be tailored to the prostate size and localisation. The TRUS technique proved to be most helpful in visualising the gland localised in the pelvic cavity, while the TAUS scanning for the enlarged, displaced cranially prostate.
