Summary
Multidetector computed tomography (CT) revealed incomplete pulmonary lobulation in 42.2% of patients. Multplanar reformation (MPR) is crucial for observing these variations and associated abnormalities.
Area of Science:
- Radiology
- Anatomy
- Thoracic Imaging
Background:
- Pulmonary lobulation variations can impact thoracic imaging interpretation.
- Previous studies on incomplete lobulation relied on different CT technologies.
Purpose of the Study:
- To investigate incomplete pulmonary lobes and their variations.
- Utilize multiplanar reformation (MPR) with multidetector CT (MDCT) data.
- Characterize the prevalence and patterns of incomplete lobulation.
Main Methods:
- 1000 patients underwent 16-row MDCT with 1mm slice thickness.
- Interlobar fissures were analyzed using scrolling MPR techniques.
- Data were analyzed for incomplete fissures and excessive fissure formation.
Main Results:
- Incomplete interlobar fissures were found in 42.2% of subjects.
- Specific incidences included right upper/middle (20.4%), right major (17.4%), and left major (19.2%) fissures.
- Excessive fissure formation occurred in 8%, with associated abnormalities in roughly half of incomplete lobulation cases.
Conclusions:
- MDCT reveals a lower incidence of incomplete lobulation than prior CT studies.
- Findings align with autopsy data, highlighting MPR's importance.
- Multidirectional observation via MPR is essential for accurate assessment.

01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

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...
01:10Computed 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...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
