Plain radiography
What is the main indication for using sialography in imaging the salivary glands?
Studying the ductal morphology
'Operator dependent, can detect small stones (>2mm), inexpensive, non-invasive' - Which imaging method does this statement describe?
High-resolution ultrasonography
'Contrast-enhanced axial CT image shows hypodense, enlarged right submandibular gland with calculus' - Which condition is most likely depicted in this image?
Sialolithiasis
'Non-contrast T2W axial & coronal images showing parotid and submandibular glands' - Which imaging technique typically uses T2-weighted images?
Magnetic resonance imaging (MRI)
'It refers to the evaluation of the ductal system of the salivary glands and is considered the gold standard technique for studying the ductal morphology' – Which imaging technique is being referred to in this statement?
Sialography
The parotid gland is the smallest major salivary gland.
False
Stensen’s duct opens opposite the second upper molar tooth.
True
Warthon’s duct drains the sublingual gland.
False
The hypoglossal nerve is in anatomical relationship with the parotid gland.
True
Sialography is mainly used to evaluate the ductal system of the salivary glands.
True
Stensen's duct has two lobes, superficial, and deep.
False
The lingual nerve is not in anatomical relationship with the parotid gland.
False
The terminal branch of the external carotid artery divides into maxillary and superficial temporal artery within the parotid gland.
True
The composition of the parotid gland is nearly isodense/isointense to fat on CT/MR images.
True
The parotid gland is composed of adipose and glandular tissues in nearly equal proportions.
True
Stensen’s duct is 4 cm long.
False
The parotid gland is drained through Warthon’s duct.
False
The submandibular gland is the largest salivary gland in the human body.
False
The sublingual gland opens via multiple ducts known as ducts of Rivinus directly into the floor of the mouth.
True
Plain radiography is useful in detecting ductal calculi, calcifications, and adjacent osseous lesions in the salivary glands.
True
High-resolution ultrasonography (HRUS) is not operator dependent and can detect small stones (>2mm) in the salivary glands.
False
CT has an upper hand over MRI in demonstrating the osseous lesions/extension and calcification/calculus in the salivary glands.
True
Sialolithiasis is characterized by inflammation and enlargement of one or more of the salivary glands.
False
Sialography is commonly used for sublingual imaging due to the presence of numerous small ducts opening directly into the floor of the mouth.
False
Radionuclide Imaging is useful preoperatively to determine if the salivary gland is functional.
True
Inflammatory diseases of salivary glands include sialadenitis which is a condition characterized by inflammation and enlargement of one or more of the salivary glands.
True
The ducts of the sublingual glands are called Wharton's ducts.
False
The lingual nerve separates the sublingual gland from the medial genioglossus muscle.
True
Sialography is considered the gold standard technique for studying the ductal morphology of all major salivary glands.
False
This quiz provides an introduction to the salivary glands, focusing on the parotid gland. It covers the composition, major and minor glands, and imaging characteristics of the parotid gland.
