Researchers used CT scans to examine 43 crocodilian species (both living and extinct) and found that the brains and inner-ear structures have changed very little over about 100 million years, suggesting an exceptionally effective brain design that helped these reptiles endure climate shifts and mass extinctions.
CT-scanning the two only complete dodo skulls (plus a third) enabled researchers to reconstruct endocasts and compare the dodo’s brain with those of pigeons, doves, and the Rodrigues solitaire. The results suggest the dodo may have foraged at dawn and dusk, had a stronger sense of smell, and used its large upper beak to feel its surroundings, implying it was smarter than many birds and offering new insights into how it lived and why it went extinct.
A tip and CT scan leak claim the iPhone 18 Pro will shrink the Dynamic Island by relocating the infrared flooder to the side (potentially under the display) while a massive vapor chamber stretches to the top. The front camera and Face ID would sit in a smaller pill-shaped cutout, and the device is said to feature a 48MP triple-camera setup, Samsung’s M16 LTPO+ OLED display with dynamic 1–120 Hz refresh, a C2 modem with 5G mmWave and satellite features, four color options, refined aluminum, and a starting price around $1,399.
Researchers at Mayo Clinic and MD Anderson developed REDMOD, an AI radiomics model that analyzes CT scans to detect pancreatic cancer years before diagnosis, flagging 46 of 63 pre-diagnosis cases (about 73%) an average of 16 months early (some up to 3 years) and outperforming radiologists, who identified signs in 38.9% of cases. The system also produced 81 false positives among 430 healthy controls. While promising across multiple datasets, researchers caution that larger, more diverse validation and smoother clinical integration are needed before use in routine care.
Oxford researchers tested a CT scan paired with the tracer maraciclatide to spot early endometriosis. In a small pilot, the technique correctly detected endometriosis in 16 of 19 cases and matched 14 of 17 surgically confirmed diagnoses, suggesting a non-invasive path to earlier diagnosis. If confirmed in larger studies, it could shorten the current diagnostic journey that often requires invasive laparoscopy and help patients start treatment sooner.
CT scans of a 2,500-year-old Pazyryk mummy from southern Siberia reveal a damaged jaw stabilized by a primitive prosthetic, likely made from elastic material, suggesting the woman survived long enough to move her jaw to a limited extent and highlighting Iron Age medical care in nomadic cultures.
A 1,100-year-old mummy of a miner found in Chile shows he died from extensive blunt-force trauma likely caused by a mine collapse, with CT scans revealing injuries consistent with a rockfall during turquoise extraction in ancient times.
Scientists used non-invasive CT and X-ray technology to examine a 3,000-year-old Egyptian crocodile mummy, revealing it was likely sacrificed and providing insights into ancient Egyptian rituals and their reverence for crocodiles, including findings of a fish and stones in its stomach that suggest it was caught and sacrificed shortly before death.
President Donald Trump clarified that he received a CT scan, not an MRI, during his October health check at Walter Reed, with his doctor confirming the procedure and results as normal, while Trump expressed regret over the imaging being used against him.
President Trump clarified that he underwent a CT scan, not an MRI, during his October health check at Walter Reed, and expressed regret about having the scan as it provided ammunition for critics; he also discussed his health regimen and lifestyle preferences.
Leticia Paul, a 22-year-old law graduate in Brazil, died from a rare allergic reaction (anaphylactic shock) caused by contrast dye during a routine CT scan, prompting an investigation into possible medical negligence and raising concerns about patient safety.
A 22-year-old lawyer in Brazil died less than 24 hours after suffering a severe allergic reaction to contrast dye during a CT scan, highlighting the risks associated with medical procedures and the importance of safety protocols.
A study estimates that the widespread use of CT scans in the US in 2023 could lead to approximately 103,000 new cancer cases over the lifetime of those exposed, highlighting the need to balance the diagnostic benefits of CT imaging with its potential long-term cancer risks, especially in children and frequent users.
A 22-year-old law graduate in Brazil died after an allergic reaction to contrast dye used during a routine CT scan for kidney stones, highlighting the rare but serious risks associated with medical imaging contrast agents.
A recent study analyzing 93 million CT scans in 2023 estimates that the radiation from these scans could lead to approximately 103,000 future cancers in the US, with higher risks in infants and children, and emphasizes the importance of justifying each scan and considering alternatives like MRI or ultrasound to reduce unnecessary radiation exposure, while acknowledging the critical diagnostic benefits of CT scans in urgent and complex cases.
