Radiology MRI

  T2 sequences showing right sided paramedian disk herniation at L5-S1 level compressing right nerve root S1 in the lateral recess. No spinal stenosis. See my YouTube Short Video

  A case of a young patient with incidental finding of an intra-dural extra-spinal Schwannoma. Tumor enhances mostly in the periphery, is well defined and shows high signal on T2 sequences. Tumor compresses conus. Note fine outcome on the control study 6 months after operation (on the right) with no residue tumor and fine remodelling of the conus.  See also my YouTube Short . 

  Young patient diagnosed with vitamin B12 deficiency showing classical inverted V sign in the posterior part of the cervical spinal cord that indicates Subacute Combined Degeneration of the spinal cord.  See also my YouTube Short :

I asked ChatGPT-4: "Can you make me an image of a simulated Lego set of an MRI Scanner. Show it in foreground with its box behind."  This is what I got:  This image was generated by AI called Dall-E that is subdivision of ChatGPT. It looks pretty impressive! It would certainly be a great present for X-mas! I was inspired to make this prompt after seeing the image below that i found on X, that also looks like generated by AI.  I think capabilities of AI in the field of Radiology are pretty impressive!  But honestly I was even more impressed when I asked ChatGPT to spot the difference between two images I took in my garden. It did the great job and this is quite promising example of how can AI be used in Radiology. See the images for yourself first and spot the difference:  And now look at result of AI analysis: As a fun task I asked AI to make me an image of a cat sitting on top of aquarium - something I'm used to see in my office. Here is what I got: I think it'...

Non-Ketotic Hyperglycemic Hemichorea (NKHH), also known as Diabetic Striatopathy, is a rare neurological disorder predominantly observed in patients (mostly Asian elderly women) with uncontrolled diabetes, usually type 2. It is characterized by involuntary, irregular, and unpredictable movements, primarily affecting one side of the body (hemichorea). The condition is linked to hyperglycemia without ketosis and often involves alterations in the basal ganglia's striatum (comprising the caudate nucleus and putamen). A 49-year-old Caucasian male with a history of type 1 diabetes presented with characteristic symptoms of hemichorea. This case is particularly noteworthy given the patient's background, as NKHH predominantly affects older individuals with type 2 diabetes. Radiological Findings: CT and MRI Analysis Image 1: Initial CT and MRI The first CT scan, performed without contrast, revealed diffusely increased signal intensity in the putamen , more pronounced on the right. The su...

  There are many congenital anomalies of the spine. One rare is this one spotted as incidental finding on MRI of the Cervical Spine of a 64 years old patient. Reporting radiologist pointed skeletal anomaly in form of an ossicle between laminae of C2 and C3 on the right side causing slight impression on the posterior part of the dural sack, recommending further analysis with CT of the Cervical Spine. The CT has confirmed what looks like an anomalous ossicle between laminae C2 and C3. The ossicle has its own cortex and there are some depressions in the laminae due to its presence.  Similar anomalous ossicle is described in T. Keats - Atlas of Normal Roentgen Variants 7th edition, Figure 3-69, page 215.
