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 III: Computed Tomography

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Design Example: Traverse Angle Computations

Design Example: Traverse Angle Computations

Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...

Area Computation by the Alternative Coordinate Method

Area Computation by the Alternative Coordinate Method

The alternative coordinate method, also known as the Shoelace Formula, is a technique for determining the area of a traverse using Cartesian coordinates. This method relies on the sequential arrangement of x and y coordinates for each point of the shape, ensuring accuracy and ease of application.In this approach, each corner's x and y coordinates are listed as fractions, with the x-coordinate as the numerator and the y-coordinate as the denominator. These coordinates are arranged sequentially...

Primary Active Transport

Primary Active Transport

In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

Positron Emission Tomography

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Spinal Surgery

Background:

Primary spinal tumors are rare compared to metastatic lesions.
Surgical management of primary spinal tumors presents unique challenges.
The role of advanced navigation in these cases requires further elucidation.

Purpose of the Study:

To evaluate the efficacy and safety of O-arm navigation-assisted surgery for primary spinal tumors.
To assess the impact of O-arm navigation on surgical outcomes, including complication rates and oncological control.

Main Methods:

A prospective study included 18 patients with primary spine tumors undergoing O-arm navigation-assisted surgery (2014-2017).
Data collected included patient demographics, tumor types, surgical approaches, and postoperative outcomes.
Outcomes assessed: navigation-related complications, resection complications, local recurrence, implant failure, and mortality.

Main Results:

No intraoperative complications related to O-arm navigation or equipment were reported.
All 18 procedures were successfully completed without abandonment.
Zero instances of screw misplacement, mechanical implant failure, or local recurrence were observed.
Various tumor types were treated, including osteoblastoma, Langerhans cell histiocytosis, and chondrosarcoma.

Conclusions:

O-arm navigation-assisted surgery offers improved safety and oncological results for primary spine tumors.
Navigation facilitates precise screw placement, leading to fewer complications during tumor resection.
This technology enhances the surgical management of complex primary spinal pathologies.
