Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Ultrasonography

Ultrasonography

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 a...

Background:

Ovarian cancer is a significant health challenge, ranking as the third most common gynecologic malignancy and a leading cause of cancer death in women.
Multi-detector computed tomography (MDCT) is a readily available and effective imaging modality for diagnosing ovarian cancer.

Purpose of the Study:

To evaluate the diagnostic performance of 64-slice MDCT in classifying ovarian masses.
To compute sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy.

Main Methods:

A prospective, cross-sectional analytical study was conducted with 105 women suspected of having malignant ovarian cancer.
Data was collected from July 2010 to August 2011 at a tertiary care hospital in Karachi, Pakistan.
Exclusion criteria included patients with histologically proven ovarian carcinoma or contraindications to radiation/contrast media.

Main Results:

Reader A achieved 92% sensitivity, 86.7% specificity, 94.5% PPV, 86.7% NPV, and 90.5% accuracy.
Reader B achieved 94.6% sensitivity, 90% specificity, 96% PPV, 87.1% NPV, and 93.3% accuracy.
Excellent inter-observer agreement was noted with a kappa value of 0.887.

Conclusions:

Multi-detector computed tomography (MDCT) is a reliable imaging modality for accurate diagnosis of ovarian masses.
The study demonstrated insignificant inter-observer variability, supporting its clinical utility.
