Scottie Dog Sign
Scottie dog sign is a radiological sign which refers to the appearance of lumbar spine in oblique view X-ray. In the X-ray, the spine can be visualised as the lateral view of a Scottie dog, with the pedicle as the eye, the transverse process as the nose, the superior articular facet as the ear and the inferior articular facet as the front leg, spinous process as the body. It was once used as a diagnostic sign in x-rays for lumbar spondylolysis, but it is not commonly in use nowadays because of the advent of more sensitive diagnostic methods such as the CT scan and MRI scan. If spondylolysis is present, the pars interarticularis, or the neck of the dog, gives the appearance of a Scottish Terrier The Scottish Terrier (; also known as the Aberdeen Terrier), popularly called the Scottie, is a dog breed, breed of dog.

Radiological Sign
A radiologic sign is an objective indication of some medical fact (that is, a medical sign) that is detected by a physician during radiologic examination with medical imaging (for example, via an X-ray, CT scan, MRI scan, or sonographic scan). Examples * Double decidual sac sign * Face of the giant panda sign * Football sign * Golden S sign * Hampton's hump * Hilum overlay sign * Kerley lines * Mickey Mouse sign * Omental cake * Peribronchial cuffing * Pneumatosis intestinalis * Rigler's sign * Westermark sign In chest radiograph A chest radiograph, chest X-ray (CXR), or chest film is a projection radiograph of the chest used to diagnose conditions affecting the chest, its contents, and nearby structures. Chest radiographs are the most common film ... See also * List of radiologic signs References {{Radiologic signs * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scottie Dog
The Scottish Terrier (; also known as the Aberdeen Terrier), popularly called the Scottie, is a breed of dog. Initially one of the highland breeds of terrier that were grouped under the name of ''Skye Terrier'', it is one of five breeds of terrier that originated in Scotland, the other four being the modern Skye, Cairn, Dandie Dinmont, and West Highland White terriers. They are an independent and rugged breed with a wiry outer coat and a soft dense undercoat. The first Earl of Dumbarton nicknamed the breed "the diehard". According to legend, the Earl of Dumbarton gave this nickname because of the Scottish Terriers' bravery, and Scotties were also the inspiration for the name of his regiment, The Royal Scots, Dumbarton's Diehard. Scottish Terriers were originally bred to hunt vermin on farms. They are a small breed of terrier with a distinctive shape and have had many roles in popular culture. They have been owned by a variety of celebrities, including the 32nd president of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spondylolysis
Spondylolysis also known as a pars defect or pars fracture, is a defect or stress fracture in the pars interarticularis of the vertebral arch. The vast majority of cases occur in the lower lumbar vertebrae (L5), but spondylolysis may also occur in the cervical vertebrae.Dubousset, J. Treatment of Spondylolysis and Spondylolisthesis in Children and Adolescents. Clinical Orthopaedics and Related Research. 1997;337:77–85. Signs and symptoms In majority of cases, spondylolysis presents asymptomatically, which can make diagnosis both difficult and incidental. When a patient does present with symptoms, there are general signs and symptoms a clinician will look for: * Clinical signs:Humphreys, D. "Lecture on Spondylolysis and Spondylolisthesis". [OWL]. Western University Kinesiology Program; 2015. ** Pain on completion of thstork test(placed in hyperextension and rotation) ** Excessive lordotic posture ** Unilateral tenderness on palpation ** Visible on diagnostic imaging (Scottie do ...

CT Scan
A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. The personnel that perform CT scans are called radiographers or radiology technologists. CT scanners use a rotating X-ray tube and a row of detectors placed in a gantry (medical), gantry to measure X-ray Attenuation#Radiography, attenuations by different tissues inside the body. The multiple X-ray measurements taken from different angles are then processed on a computer using tomographic reconstruction algorithms to produce Tomography, tomographic (cross-sectional) images (virtual "slices") of a body. CT scans can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is Contraindication, contraindicated. Since its development in the 1970s, CT scanning has proven to be a versatile imaging technique. While CT is most prominently used in medical diagnosis, i ...

MRI Scan
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from computed tomography (CT) and positron emission tomography (PET) scans. MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy. MRI is widely used in hospitals and clinics for medical diagnosis, staging and follow-up of disease. Compared to CT, MRI provides better contrast in images of soft tissues, e.g. in the brain or abdomen. However, it may be perceived as less comfortable by patients, due to the usually longer and louder measurements with the subject in a long, confining tube, although "ope ...
