The Who and Why of MRI
While chest computed tomography CT is the mainstay for initial evaluation of mediastinal masses detected incidentally by radiography or by clinical presentation, CT results are frequently indeterminate. Thoracic magnetic resonance imaging MRI offers a noninvasive way to further characterize mediastinal lesions, their site of origin, and their involvement of adjacent structures. Its higher soft-tissue contrast than CT yields superior tissue characterization and often provides more diagnostic specificity.
Thoracic MRI has been shown to significantly alter clinical management, reduce the need for patient follow-up, and lower the surgical intervention rate. As is true elsewhere in the body, MRI allows improved differentiation of cystic from solid lesions and better distinction between simple and complex cystic lesions in the thorax. Chemical shift gradient echo MR imaging in- and opposed-phase imaging detects microscopic fat; fat-saturation techniques identify macroscopic fat.
Relative cerebral blood volume (rCBV) imaging, which is derived from dynamic bright T1 signal that might result, for example, from blood products. MRI exam were censored if the time between the last exam and date of.
The MRI appearances of blood are dependent on the oxidation state of hemoglobin and its environment. The appearances of hemorrhage vary with time in adult patients allowing the lesion to be aged Table 9. The signal intensity of a hemorrhagic lesion also depends on the field strength of the magnet and the sequence used to obtain the image; as a rule the evolution of hemorrhage appears faster at lower field strengths. In our experience the evolution of cerebral hemorrhage in the immature brain is similar to that in the adult, although we have relatively few examples of perinatally acquired parenchymal hemorrhage before 3 days of age.
The evolution of small parenchymal hemorrhagic lesions is not so typical as they may not show a persistent long T2 component. Table 9. Extracerebral hemorrhage appears to behave slightly differently from parenchymal hemorrhage. Large intraventricular hemorrhages with clot within the ventricular system may have a long T2 component seen between 3 days and 3 weeks but this is not seen in smaller hemorrhages.

With incorporation of creatinine analyses to blood gas and other point-of-care platforms the test is now available outside the laboratory, at the bedside and in the clinic. This is the first of two articles that highlight the clinical value of creatinine measurement in the radiology department. An ever-increasing number of patients submitted for X-ray and other body imaging examinations such as computed tomography CT and magnetic resonance imaging MRI scan are given image-enhancing contrast agents that can be associated with adverse effect.
Among these adverse effects are two conditions that are the focus of the two articles: nephrogenic systemic fibrosis NSF and contrast-induced nephropathy CIN. Consideration of the significance of serum creatinine measurement in CIN is reserved for the second article. Here the focus is NSF and how measurement of serum creatinine is used to identify those patients at risk of the condition.

The history of magnetic resonance imaging MRI includes the work of many researchers who contributed to the discovery of nuclear magnetic resonance NMR and described the underlying physics of magnetic resonance imaging , starting early in the twentieth century. MR imaging was invented by Paul C. Lauterbur who developed a mechanism to encode spatial information into an NMR signal using magnetic field gradients in September ; he published the theory behind it in March The first clinical MRI scanners were installed in the early s and significant development of the technology followed in the decades since, leading to its widespread use in medicine today.
In , spin echoes and free induction decay were first detected by Erwin Hahn   and in , Herman Carr produced a one-dimensional NMR spectrum as reported in his Harvard PhD thesis. The next step from spectra to imaging was proposed by Vladislav Ivanov in Soviet Union , who filed in a patent application for a Magnetic Resonance Imaging device. In modern terms, it was only proton-density not relaxation times imaging, which was also slow since, only one gradient direction was used at a time and the imaging had to be done slice-by-slice.
Nevertheless, it was a true Magnetic Resonance Imaging procedure. Originally rejected as “improbable”, Ivanov’s application was finally approved in with the original priority date. By , Jay Singer had studied blood flow by NMR relaxation time measurements of blood in living humans. In the s and s the results of work on relaxation, diffusion, and chemical exchange of water in cells and tissues of various types appeared in the scientific literature.
Damadian’s initial methods were flawed for practical use,  relying on a point-by-point scan of the entire body and using relaxation rates, which turned out not to be an effective indicator of cancerous tissue. He patented such a machine, U.

There are many factors your doctor will rely on to form an accurate multiple myeloma diagnosis — overall health, symptoms and diagnostic tests of blood, urine and bone marrow play an important role. Being diagnosed with a disease like multiple myeloma can feel overwhelming. These are some of the steps you can take to begin management of your disease.
Knowing the classification of your disease is very important in deciding when it is appropriate to begin treatment. Classification also plays an important role in determining the stage of multiple myeloma. MGUS is a plasma cell neoplasm diagnosed when a small amount of M protein is detected in the blood, but no other criteria for a solitary plasmacytoma or multiple myeloma diagnosis such as a tumor, multiple lesions or symptoms are present.
People living with MGUS receive regular checkups to ensure that it does not progress. Isolated plasmacytoma of the bone can affect any bone, but tends to occur most frequently in the bones along the spinal column. Solitary plasmacytoma within the bone is normally diagnosed by a biopsy that reveals abnormal plasma cells.

For example, muscle injury, cellulitis a bacterial skin infection , and inflammation swelling of veins that are just under the skin can mimic the signs and symptoms of DVT. It is important to know that heart attack and pneumonia can have signs and symptoms similar to those of PE. Therefore, special tests that can look for clots in the veins or in the lungs imaging tests are needed to diagnose DVT or PE.

John C. Wood; Guidelines for quantifying iron overload. Both primary and secondary iron overload are increasingly prevalent in the United States because of immigration from the Far East, increasing transfusion therapy in sickle cell disease, and improved survivorship of hematologic malignancies. This chapter describes the use of historical data, serological measures, and MRI to estimate somatic iron burden.
Before chelation therapy, transfusional volume is an accurate method for estimating liver iron burden, whereas transferrin saturation reflects the risk of extrahepatic iron deposition. In chronically transfused patients, trends in serum ferritin are helpful, inexpensive guides to relative changes in somatic iron stores. However, intersubject variability is quite high and ferritin values may change disparately from trends in total body iron load over periods of several years.

To document the signal characteristics of intracerebral hemorrhage ICH at evolving stages on diffusion-weighted images DWI by comparison with conventional MR images. DWI showed that hematomas were hyperintense at the hyperacute and late subacute stages, and hypointense at the acute, early subacute and chronic stages. Invariably, focal hypointensity was observed within a hyperacute hematoma.
At the hyperacute, acute and early subacute stages, hyperintense rims that corresponded with edema surrounding the hematoma were present. The mean ADC ratio was 0. In patients with acute stroke, an understanding of the characteristic features of ICH seen at DWI can be helpful in both the characterization of intracranial hemorrhagic lesions and the differentiation of hemorrhage from ischemia.
