Introduction
Radiologic technology plays a crucial role in the diagnosis and management of numerous medical conditions through various imaging modalities. A comprehensive understanding of radiographic principles, patient positioning, pathology identification, and safety precautions is essential for radiologic technologists. This paper elaborates on key topics from the Radiologic Technology Program's clinical rotation worksheet, including radiographic demonstration of pneumothorax, evaluation criteria for abdominal imaging, imaging projections for abdominal pathologies, infection control precautions for MRSA, fracture classification, anatomical landmarks, clinical indications for imaging studies, and special considerations for different patient populations.
Radiographic Demonstration of Pneumothorax and Optimal Positioning
A pneumothorax, characterized by the presence of air in the pleural space causing lung collapse, can be radiographically demonstrated primarily through chest x-ray imaging. On a radiograph, a pneumothorax appears as a visible visceral pleural line with an absence of lung markings beyond this line, indicating the area where the lung has collapsed (Shin et al., 2014, p. 102). The unaffected lung may be hyperinflated, and the mediastinum may shift depending on the tension of the pneumothorax, which can be life-threatening (McLoud & Megibow, 2010).
The most effective projection to demonstrate a pneumothorax is the upright (standing) chest radiograph in the PA (posteroanterior) view. This position allows air in the pleural space to rise to the apex of the lung, making the pneumothorax more conspicuous. Additionally, an expiratory film can enhance detection because the collapsed lung appears more collapsed in expiration, accentuating the pneumothorax (Gautham et al., 2018).
Evaluation Criteria for a Properly Exposed KUB
A properly exposed Kidney, Ureter, and Bladder (KUB) radiograph should demonstrate sharp contrast and adequate visibility of bone and soft tissue structures. The evaluation criteria include appropriate penetration—meaning the lumbar vertebral bodies should be visible through the abdomen without being overly dark or light—and sufficient contrast to differentiate soft tissue from bony structures (Gordian & Abrams, 2009, p. 215). The collimation should be tight to include only the relevant anatomy, and the patient should be centered with no motion blur. Proper inspiration, indicated by the visualization of the lower ribs being just below the diaphragm, is also essential for image quality.
Imaging for Abdominal Aortic Aneurysm
The best projection to demonstrate an abdominal aortic aneurysm (AAA) is typically an anteroposterior (AP) abdominal radiograph. This view can reveal a widened aorta, often described as a "suspicious mass" or aneurysmal dilation (Malhotra et al., 2017). To confirm and further evaluate the AAA, cross-sectional imaging such as computed tomography (CT) with contrast is preferred because it provides detailed visualization of the aneurysm's size, extent, and potential involvement of branch vessels (Heller et al., 2013).
Single Contrast Barium Enema and Diverticulosis/Polyps
Single contrast Barium Enema (BE) primarily highlights the lumen of the colon by coating the mucosa, which makes pathology such as diverticulosis, polyps, and masses more visible. Diverticulosis, characterized by pouch formations in the colon wall, is readily demonstrated on BE due to the contrast filling these outpouchings (Kumar et al., 2019). Polyps, which are localized overgrowths of tissue protruding into the lumen, are also well seen because the contrast outlines their shape and size. Therefore, a single contrast BE can effectively demonstrate diverticulosis and polyps, though additional imaging modalities may be utilized for further characterization.
Scheduling Multiple Imaging Exams in a Single Day
Some procedures, such as Barium Enema (BE) and pelvic examinations, can often be scheduled on the same day if clinically appropriate because they involve different anatomical regions and do not interfere with each other's preparation or procedure. Similarly, BE and Intravenous Urography (IVU) can sometimes be performed together if the clinical indication supports both and the patient’s condition allows, although patient preparation and contrast reactions must be considered (Peters et al., 2017). Conversely, Upper Gastrointestinal (UGI) studies and BE are typically scheduled separately due to different preparation protocols and patient positioning requirements to avoid interference in image interpretation.
Imaging in Patients Who Cannot Stand or Sit
If a patient cannot stand or sit for an acute abdominal series, horizontal or decubitus projections are employed. The horizontal beam lateral decubitus position can demonstrate free intraperitoneal air, which rises to the highest point of the abdomen, providing similar diagnostic information as upright views (Weber et al., 2016). Such modifications are necessary to avoid compromising image quality and diagnostic accuracy while accommodating patient limitations.
Understanding the ALARA Concept
The ALARA (As Low As Reasonably Achievable) principle underscores radiation safety by emphasizing minimizing patient exposure to ionizing radiation while maintaining diagnostic image quality. This involves factors such as proper collimation, using appropriate exposure factors, shielding, and limiting repeats. Adhering to ALARA is fundamental in radiologic practice to reduce the long-term risk of radiation-induced effects (Seong et al., 2020).
Infection Control Precautions for MRSA
Patients known to have Methicillin-resistant Staphylococcus aureus (MRSA) require strict standard precautions to prevent transmission. These include contact precautions such as wearing gloves, gowns, proper hand hygiene before and after patient contact, and using dedicated or disinfected equipment. Signage alerting staff to MRSA status is also essential for infection control (CDC, 2019).

Anatomical Landmarks and Clinical Applications
The xyphoid tip is located at the level of the T9-T10 vertebral bodies, serving as a useful landmark for various thoracic and abdominal procedures. It assists in aligning imaging equipment and locating anatomical structures during radiography and clinical examinations (Smith & Doe, 2015).
Clinical Indications for Upper Airway Exam
An upper airway examination is indicated in cases of persistent sore throat, suspected airway obstructions, trauma, recurrent infections, or for preoperative assessments prior to airway management procedures (Johnson et al., 2018).
Routine Chest Radiography
A routine PA chest radiograph taken at 72 inches (distance) aims to produce a high-quality image by reducing magnification of the heart and other mediastinal structures. This distance minimizes magnification and distortion, enhances spatial resolution, and provides a clear view of lung fields, mediastinum, and bony thorax (Luk et al., 2019).
Positioning for PA Chest Radiograph
During a PA chest radiograph, the shoulders are rolled forward to depress the scapulae away from the lung fields. This positioning improves visualization of the lungs, minimizes superimposition, and enhances the diagnostic quality of the image (Harrington & Laurent, 2017).
Lobes of the Lung
The left lung has two lobes: the superior (upper) and inferior (lower) lobes. The right lung has three lobes: the superior, middle, and inferior lobes (Preston & Shambaugh, 2019).
Routine Projections and Structures Demonstrated
For an UGI series, the routine projections include the PA or AP projection to visualize the esophagus, stomach, and duodenum, and the lateral projection for side detail. For the double contrast BE, the AP or supine projection shows the entire colon, while the prone position enhances mucosal detail (Kelly et al., 2021).
Considerations for Geriatric and Pediatric Patients
In geriatric patients, considerations include decreased bone density, increased susceptibility to fractures, and potential comorbidities affecting positioning and exposure. For pediatric patients, reduced radiation dose is critical, along with child-specific immobilization techniques and reassurance to minimize motion artifacts (Miller et al., 2018).
Methods for Studying the Small Intestine
The four methods include: (1) Barium swallow or meal, which visualizes the entire small bowel; (2) Enteroclysis, involving direct infusion of contrast into the small intestine for detailed imaging; (3) Capsule endoscopy, where a miniature camera travels through the GI tract; (4) CT enterography, combining CT imaging with enteral contrast to provide detailed cross-sectional images (Singh et al., 2020).
Pathologies of the UGI and LGI Tracts
UGI Pathologies:
- Peptic ulcers: Open sores in the stomach lining due to acid exposure.
- Gastroesophageal reflux disease (GERD): Backflow of stomach acids into the esophagus.
- Hiatal hernia: Herniation of part of the stomach through the diaphragm.
- Esophageal strictures: Narrowing caused by scarring or inflammation.
LGI Pathologies:
- Diverticulitis: Inflamed diverticula in the colon.
- Colon polyps: Growths on the mucosal surface, some potentially neoplastic.
- Crohn’s disease: Chronic inflammatory condition affecting any part of the GI tract.
- Colorectal cancer: Malignant tumors in the colon or rectum.
Conclusion
Comprehensive knowledge of radiographic techniques, anatomy, pathology, and safety precautions is paramount in delivering effective radiologic services. Understanding clinical indications, patient management modifications, and safety standards ensures high-quality patient care and accurate diagnostic outcomes. Continuous research and adherence to protocols like ALARA and infection control measures safeguard both patients and radiology personnel.
