Ultrasonography01:17

Ultrasonography

7.4K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Metallic Solids02:37

Metallic Solids

20.5K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Structures of Solids02:22

Structures of Solids

17.5K
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...

Ultrasound I: Abdominal Ultrasonography

1.4K
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Network Covalent Solids02:18

Network Covalent Solids

16.1K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Summary
This summary is machine-generated.

Endoscopic ultrasonography (EUS) is a reliable tool for detecting and staging pancreatic cancer. Combining EUS with contrast-enhanced harmonic EUS (CH-EUS) and EUS-guided fine-needle aspiration (EUS-FNA) improves diagnostic accuracy for pancreatic solid lesions.

Area of Science:

  • Gastroenterology
  • Medical Imaging
  • Oncology

Background:

  • Pancreatic cancer incidence and mortality are rising, with a poor prognosis.
  • Endoscopic ultrasonography (EUS) offers superior resolution for diagnosing pancreatic diseases compared to CT and MRI.
  • EUS is crucial for detecting pancreatic solid lesions and staging cancer.

Purpose of the Study:

  • To review the utility of EUS, contrast-enhanced harmonic EUS (CH-EUS), and EUS-guided fine-needle aspiration (EUS-FNA) in diagnosing pancreatic solid lesions.
  • To highlight the role of EUS in screening high-risk individuals for pancreatic cancer.
  • To emphasize the combined diagnostic power of EUS-based techniques.

Main Methods:

  • Review of current literature on EUS, CH-EUS, and EUS-FNA for pancreatic diseases.
  • Analysis of EUS's capabilities in lesion detection, characterization, and staging.
  • Evaluation of EUS-FNA's cytopathological diagnostic accuracy and the impact of CH-EUS.

Main Results:

  • EUS is effective for detecting and staging pancreatic cancer, and screening high-risk patients.
  • CH-EUS aids in differentiating hypoechoic pancreatic lesions, improving characterization.
  • EUS-FNA provides superior cytopathological diagnosis; combining it with CH-EUS reduces false negatives.

Conclusions:

  • Conventional EUS, CH-EUS, and EUS-FNA are essential for diagnosing pancreatic solid lesions.
  • The integration of these EUS-based modalities enhances diagnostic accuracy and clinical management.
  • These techniques are vital for improving outcomes in patients with pancreatic cancer.
