Abstract
Accurate interpretation of thoracic magnetic resonance images requires a thorough knowledge of anatomy of this region. The purpose of this communication is to describe the normal cross sectional anatomy of the thoracic cavity of the cat, using MR images, dissections and macroscopic sections. In this study, three cats were used. The animals were anesthetized and positioned in sternal recumbency in the MR scanner. MR imaging was performed at the Special Diagnostic Service of San Roque Clinic of Las Palmas de Gran Canaria with a superconducting magnet operating at a field strength of 1.5 Tesla and a human body coil. Spin echo pulse sequences were used to obtain T1‐weighted images in tranverse and sagittal planes. At the conclusion of imaging, the cats were euthanatized for medical reasons unrelated to disease of thorax. The cats were frozen and then sectioned using an electric band saw. The cuts were matched as closely as possible to the MR images for identifying the normal planimetric anatomy of the thoracic structures. MR T1‐weighted spin echo images provided excellent anatomic appearance of the thorax structures. In MR images the grey scale is directly related to the signal intensity of the thoracic cavity structures. Thus, fat and nerves had higher signal intensity compared with the lower signal intensity of the respiratory system. Bone marrow and muscles had a intermediate signal intensity and appeared gray. The intensity signal of the articular fluid permits a good differentiation of the opposing cartilage surfaces on all MR images. The planimetric or sectional anatomy of the thoracic cavity in the cat allows a correct morphologic and topographic evaluation of the anatomic structures, being helpful tool for the identification of the MR images. The information presented should serve as an initial reference to evaluate MR images of the feline thorax and to assist interpretation of lesions of this region.

The purpose of this communication is to describe the normal cross sectional anatomy of the thoracic cavity of the cat, using MR images, dissections and macroscopic sections. In this study, three cats were used. The animals were anesthetized and positioned in sternal recumbency in the MR scanner. MR imaging was performed at the Special Diagnostic Service of San Roque Clinic of Las Palmas de Gran Canaria with a superconducting magnet operating at a field strength of 1.5 Tesla and a human body coil. Spin echo pulse sequences were used to obtain T1‐weighted images in tranverse and sagittal planes. At the conclusion of imaging, the cats were euthanatized for medical reasons unrelated to disease of thorax. The cats were frozen and then sectioned using an electric band saw. The cuts were matched as closely as possible to the MR images for identifying the normal planimetric anatomy of the thoracic structures. MR T1‐weighted spin echo images provided excellent anatomic appearance of the thorax structures. In MR images the grey scale is directly related to the signal intensity of the thoracic cavity structures. Thus, fat and nerves had higher signal intensity compared with the lower signal intensity of the respiratory system. Bone marrow and muscles had a intermediate signal intensity and appeared gray. The intensity signal of the articular fluid permits a good differentiation of the opposing cartilage surfaces on all MR images. The planimetric or sectional anatomy of the thoracic cavity in the cat allows a correct morphologic and topographic evaluation of the anatomic structures, being helpful tool for the identification of the MR images. The information presented should serve as an initial reference to evaluate MR images of the feline thorax and to assist interpretation of lesions of this region.</abstract><relatedItem type="host"><titleInfo><title>Anatomia, Histologia, Embryologia</title></titleInfo><genre type="journal">journal</genre><identifier type="ISSN">0340-2096</identifier><identifier type="eISSN">1439-0264</identifier><identifier type="DOI">10.1111/(ISSN)1439-0264</identifier><identifier type="PublisherID">AHE</identifier><part><date>2005</date><detail type="volume"><caption>vol.</caption><number>34</number></detail><detail type="supplement"><caption>Suppl. no.</caption><number>s1</number></detail><extent unit="pages"><start>43</start><end>44</end></extent></part></relatedItem><identifier type="istex">E18D271EA0CF01A2688425403132897F851729D0</identifier><identifier type="DOI">10.1111/j.1439-0264.2005.00669_98.x</identifier><identifier type="ArticleID">AHE669_98_98</identifier><recordInfo><recordContentSource>WILEY</recordContentSource><recordOrigin>Blackwell Verlag GmbH</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
