Unreliable RAM can cause a multitude of problems. Corrupted data, crashes and unexplained behaviour.
Bad RAM is one of the most frustrating computer problems to have as symptoms are often random and hard to pin down. MemTest86 can help diagnose faulty RAM (or rule it out as a cause of system instability). As such it is often used by system builders, PC repair stores, overclockers & PC manufacturers.
Since MemTest86 v5, the software is offered as a Free edition, or as a paid for Pro and Site edition. The Pro edition offers a number of additional features such as customizable reports & automation via a configuration file. The Site edition includes all features in the Pro Edition but also supports scalable deployment of MemTest86 across LAN via PXE boot.
Here are some examples of how common pathologies appear on radiographs:
For specific case studies or rare pathologies, searching Google Scholar can lead you to PDF case reports uploaded by doctors and technologists. These are excellent for continuing education credits.
Ideal for acute trauma, brain hemorrhages, and complex fractures.
: Free air in the pleural space causing a complete lack of lung markings (Destructive).
Every chapter in both major textbooks begins with normal anatomy and physiology. Do not skip this section. You cannot recognize abnormal findings without a crystal-clear mental image of normal anatomy.

Often used in digital formats in radiologic science programs.
Ultimately, a technologist well-versed in pathology acts as the radiologist’s eyes in the examination room. Recognizing an urgent pathological condition—such as a free air bubble under the diaphragm indicating a bowel perforation—allows the technologist to expedite image transmission and immediately alert the reading physician. This knowledge transforms the technologist from an equipment operator into a critical member of the diagnostic healthcare team.
Pathological conditions change the composition of human tissue. Additive diseases (like pneumonia or ascites) increase tissue density, requiring an increase in kilovoltage (kVp) or milliampere-seconds (mAs). Conversely, destructive diseases (like osteoporosis or emphysema) decrease tissue density, requiring a reduction in exposure factors. Provides digital previews and access to key chapters
Inflammation of small pouches (diverticula) in the intestinal wall, often visualized during barium enemas or CT scans.
Destructive diseases cause tissue to break down, decreasing its mass or density. Because the tissue is less dense, it absorbs less radiation. Technologists must (typically mAs) to prevent overexposing the image receptor.
