19 Possible Causes for Artefact - Patient Movement, Nausea

  • Depression

    Excessive movement or other artefact meant that three patients were removed from the ASL analyses and four from the RSFC (SI Appendix), leaving sample sizes of 16 (mean age[nature.com] The present report discusses the case of a 70-year-old woman admitted to our institution due to sudden-onset nausea and vomiting.[ncbi.nlm.nih.gov] Sometimes these emotions can show up in the body as aches or nausea. These feelings can also lead to weepiness.[goodtherapy.org]

  • Endometriosis

    This reduces imaging time, movement artefacts, is more comfortable for the patient and is easier for workflow coordination.[ncbi.nlm.nih.gov] They may also complain of nausea, bloating and pain during or after exercise.[symptoma.com] Clinical case: A 28-year-old female patient with abdominal pain in the right iliac fossa and pelvic cavity, fever and nausea, exploratory laparotomy is performed with the[medigraphic.com]

  • Intracerebral Hematoma

    A complete study requires much more time than a CT scan and the spontaneous movements of a partially obtunded patient may cause imaging artefacts and significantly prolong[intechopen.com] These are often related to vision although may also include other symptoms such as nausea, dizziness or pins and needles.[sportsinjuryclinic.net] […] paralysis in the face, arm or leg, especially on only one side of the body Sudden severe headache Trouble with vision in one or both eyes Trouble with language skills Confusion Nausea[columbianeurosurgery.org]

  • Mesenteric Vein Thrombosis

    In contrast to MRI, CT is usually faster in providing results with fewer artefacts due to patient movement and is available 24 h/day.[karger.com] In the acute setting, a sudden onset of nonspecific abdominal pain is the principal manifestation, followed by nausea, vomiting, diarrhea and gastrointestinal bleeding (hematemesis[symptoma.com] In this case , abdominal pain , nausea, vomiting and diarrhea appeared nine days after surgical procedure .[thejh.org]

  • Progressive Myoclonic Epilepsy Type 7

    Further, some of the original patient imaging data could not be included in the texture analysis because of the suboptimal image quality caused by myoclonic movement artefacts[journals.plos.org] […] epilepsy, depression, etc - Integrative Oncology: Anticancer therapies; tumour regression, tumour suppression, antibodies, etc and Supportive cancer therapies; pain relief, nausea[ots.at] VPA (20-40 mg/kg/day) tolerability is usually good, and common side effects may include drowsiness, nausea, weight increase, postural tremor.[ncbi.nlm.nih.gov]

  • Dissociative Identity Disorder

    The data of three actors and one patient were excluded due to huge movement artefacts and low signal quality.[ncbi.nlm.nih.gov] They may present as a complaint of blushing, hand tremor, nausea, or urgency of micturition, the patient sometimes being convinced that one of these secondary manifestations[web.archive.org] One patient had fallen asleep during the ANP and had switched several times during the EP run.[ncbi.nlm.nih.gov]

  • Teratoma

    New modern devices (helical and multisclice devices) allow very thin jointive slices, with minimal patient irradiation, performed in a short time thus eliminating artefacts[cology4u.blogspot.com] A 27-year-old woman with no past medical history was admitted to the hospital for evaluation of nausea, epigastric discomfort and loose stools.[archivesofmedicine.com] Persistent nausea monosynaptic uricolytic coracoid Mac.[mulcyber.toulouse.inra.fr]

  • Congenital Spinal Cord Anomaly

    Relative advantages of sonography over MRI include wide and cheap availability, no need for sedation or general anesthesia, and lack of vulnerability to artefacts due to patient[ijri.org] Symptoms associated with an arachnoid cyst can include headaches, nausea and vomiting, seizures, hearing and visual disturbances and difficulties with balance and walking.[cedars-sinai.edu] movement, cerebrospinal fluid (CSF) pulsation, and vascular flow which can adversely affect MR image quality. [2] In newborns and infants, the spinal arches are predominantly[ijri.org]
