Imaging Studies VII: Vascular Imaging01:19

Imaging Studies VII: Vascular Imaging

253
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

157
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Imaging Studies for Cardiovascular System V: CT

225
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Imaging Studies for Cardiovascular System IV: CMRI

275
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Spinal Cord: Cross-sectional Anatomy

3.9K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.
Gray Matter and its Components
Central to the gray matter is...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

452
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Area of Science:

  • Veterinary Neurology
  • Developmental Biology
  • Congenital Malformations

Background:

  • Split cord malformation (SCM) is a rare congenital anomaly characterized by the division of the spinal cord.
  • This condition can lead to significant neurological deficits and structural abnormalities.
  • Understanding the full spectrum of SCM is crucial for diagnosis and management.

Observation:

  • A calf exhibited severe cervicothoracic kyphoscoliosis and an interscapular dermal sinus with cerebrospinal fluid (CSF) leakage.
  • Magnetic resonance imaging (MRI) confirmed complete duplication of the spinal cord at the cervical intumescence.
  • Associated findings included syringohydromyelia, vertebral malformations, cerebellar vermis herniation, meningoencephalocele, and calvarial defects.

Findings:

  • The case highlights a complex presentation of split cord malformation in a bovine.
  • Complete spinal cord duplication was the central finding, accompanied by extensive vertebral and neurological malformations.
  • The association of SCM with dermal sinus, CSF drainage, and other central nervous system defects was notable.

Implications:

  • This detailed case report expands the understanding of SCM's phenotypic variability in veterinary neurology.
  • It underscores the importance of advanced imaging in diagnosing complex congenital spinal cord anomalies.
  • Further research into the embryological basis of such extensive SCM presentations is warranted.
